Resist the Squircle Jail

2026-07-08T09:37:00+02:00

With Cyberduck 9.5 with have adopted the user interface for Liquid Glass, but the application icon with the duck objects tinted colours always remaining yellow and escapes the squircle jail imposed by default on application icons on macOS 26. We posted about this on @cyberduck back in September last year.

With the recent blog post Free the Icons from Paul Kafasis this has again gained some traction from other developers and we sure hope others join like the fine folks from Cryptomator. The application icon of Mountain Duck concedes we have to admit.

For the technically interested, this is implemented as a simplistic Dock Tile Plugin.

Windows ARM

2026-06-18T17:39:00+02:00

Mountain Duck 5.3 and later runs natively on Windows 11 for ARM.

Embrace Rounded Corners

2026-06-18T16:18:00+02:00

Cyberduck 9.5 adopts user interface changes known as Liquid Glass in macOS Tahoe. Besides rounded corners, the update also includes other refinements the list of bookmarks and editing connection details in the bookmark window.

Connect Options

Controls for unavailable connect options depending on the current protocol selection are hidden but the Open Connection window now features the all available options likewise the Edit Bookmark window. Non-frequent options have been moved to a More Options tab. Additionally a Connect button is available when editing a bookmark.

Browser Window

in the main window, the navigation bar is only shown in list and outline view but not when not applicable when displaying bookmarks. Additionally a progress indicator is shown for the bookmark when a connection is being opened.

Simplify S3 Access with AWS IAM Identity Center

2026-06-18T12:57:00+02:00

Managing access to Amazon S3 across multiple AWS accounts and users has traditionally required juggling access keys, secret credentials, and complex IAM policies. With support for AWS IAM Identity Center (formerly AWS Single Sign-On) now available in Cyberduck 9.5.0 and Mountain Duck 5.3.0, connecting to S3 has never been easier or more secure.

What is AWS IAM Identity Center?

AWS IAM Identity Center is AWS’s centralized access management solution that lets users sign in once using their existing corporate credentials—whether that’s through Okta, Microsoft Entra ID (formerly Azure AD), or other identity providers. Instead of managing permanent access keys, users get short-lived credentials that automatically expire, significantly improving your security posture.

Why Use IAM Identity Center with S3?

Traditional S3 access requires creating and managing AWS access keys for each user. These long-lived credentials pose security risks if accidentally exposed or shared. IAM Identity Center solves this by:

Single Sign-On: Users authenticate once with their corporate credentials
Short-lived credentials: Temporary credentials that automatically expire and rotate. No more permanent access keys to manage or rotate
Centralized management: Control access across multiple AWS accounts from one place

Getting Started

Setting up IAM Identity Center authentication for S3 requires two main steps:

1. Configure AWS IAM Identity Center

First, enable IAM Identity Center in your AWS account and configure your identity source. You can use AWS’s built-in directory or connect to an external identity provider like Microsoft Entra ID or Okta. Create a permission set that defines what S3 resources users can access—for example, read-only or full access to specific buckets. Add users through IAM Identity Center (or sync them from your external identity provider) and assign them to AWS accounts with the appropriate permission sets. Users will receive an invitation to set up their access to the AWS access portal.

3. Connect in Cyberduck or Mountain Duck

Creating a connection is straightforward:

Create a new bookmark and select AWS S3 (IAM Identity Center) from the protocol dropdown
Provide your SSO region and start URL when prompted
Authenticate through your web browser using your corporate credentials
Approve access to Cyberduck or Mountain Duck in the AWS portal
Choose the AWS Account ID shown when your user has access to multiple accounts and the Permission Role Name if more than a single permission set is configured

The browser will redirect back to the application, and you’re connected—no access keys to copy or store.

Streamlined Workflow with AWS CLI Integration

For teams already using the AWS CLI, Cyberduck and Mountain Duck can read configuration directly from your ~/.aws/config file. Simply configure your profile once with aws configure sso, allowing you to skip the manual input.

Get Started

AWS IAM Identity Center support is available now in Cyberduck 9.5 and Mountain Duck 5.3. For detailed setup instructions and configuration options, check out our complete tutorial.

Mountain Duck 5 now available in the Mac App Store

2025-11-26T12:04:00+01:00

Version 5 is now available in the Mac App Store as a subscription instead of a perpetual license. If you previously purchased Mountain Duck in the Mac App Store, you are eligible to run version 5 with no limitations for up to one year after your purchase date before you are required to purchase a monthly or yearly subscription.

Unfortunately we cannot distribute version 4 any longer in the Mac App Store and it is not possible to support subscriptions through the Volume Purchase Program (VPP) in the Apple Business Manager or Apple School Manager. We advise to use a different solution to distribute software for users and switch to perpetual licensing we offer for Mountain Duck outside the Mac App Store.

New Application Icon for Mountain Duck

2025-10-30T11:47:00+01:00

The new application icon designed by Katharina Hagemann now comes in three variants for macOS 26 Tahoe including Dark and Mono variants. We have decided to make it squircled to fit into the new icon paradigma. The changes will be available in version 5.1.

New Status Bar Icons

Also the status bar icon in the status bar on macOS and the system tray on Windows as the main user interface to configure Mountain Duck has been revamped to visually fit better and show sync progress with rotating arrows.

Mountain Duck 5

2025-08-19T11:12:00+02:00

We are thrilled to announce Mountain Duck 5, the premier choice to mount server and cloud storage as a disk in Finder on macOS and the File Explorer on Windows. Version 5 is a solid major upgrade in development for several years with many new features and refinements, including a new Integrated Connect Mode, storage-independent file versioning support, and SMB connections.

New Features

Integrated Connect Mode

Mountain Duck 5 features a new Integrated connect mode using native APIs on Windows & macOS to integrate in the file explorer. No device driver installation or network mount required. The connect mode delivers significantly faster file write performance and file operations that match the speed of local disk operations, and a user experience similar to OneDrive on Windows or iCloud Drive on macOS but with any cloud storage provider of your choice.

Windows Search and Spotlight on macOS can be used to search for files on remote storage in Integrated connect mode.

See also the blog post Integrated Connect Mode for this feature.

SMB Support

As already available in Cyberduck, Mountain Duck 5 expands its protocol support with the addition of SMB (Server Message Block), enabling seamless connectivity to Windows file shares, Linux Samba, macOS File Sharing & Azure File Shares.

See also dedicated blog post SMB Protocol Support for this feature.

Activity Window

Track and cancel currently running sync operations in the new Activity panel available from the status bar (macOS) or tray (Windows) menu. It shows all running operations on files, pending sync tasks as well as any pending mount process.

Custom Versioning

The new Custom Versioning feature allows to safeguard and restore previous file versions. The previous version is stashed away before overwriting a file.

The option is available for all protocols with no support of file versioning such as FTP, SFTP or WebDAV ensuring your files are protected with version history regardless of the underlying storage protocol. File versions can be view and restored in the Info window.

See also the blog post Custom Versioning for this feature.

Pricing

Version 5 is the first paid upgrade after version 4 debuted in June 2020 with 17 free minor updates released since. Users with a license for version 4 receive an upgrade discount between 20% to 100%.

Integrated Connect Mode

2025-08-12T17:02:00+02:00

The new Integrated connect mode in Mountain Duck 5 synchronizes files and folders from a directory on the local disk with support from macOS and Windows.

While the Online and Smart Synchronization modes use device driver on Windows and NFS on macOS respectively to mount connections, the Integrated mode uses the tightly integrated File Provider (macOS) and Cloud Files (Windows) APIs to sync files from regular folder on the local disk like iCloud or OneDrive does. It allows faster writing and copy processes and access to cached content when offline.

Synchronization

The usage of dedicated operating system features for syncing make Mountain Duck 5 future proof. Like in Smart Synchronization connect mode, files are displayed as placeholders, cached on local disk and optionally selected to always keep offline.

The improved user experience includes familiar file management controls directly within Finder and Windows Explorer, allowing users to easily select files to keep offline, remove cached data, or exclude items from synchronization. Visual indicators provide instant feedback on synchronization status through additional icons displayed next to filenames. Real-time progress is shown during file transfers with progress bars over file icons and circular progress indicators, giving users complete visibility into upload and download operations.

Additional Context Menu Items

Additional context menu items in Windows Explorer and Finder.app on macOS provided by the system allow to download files or free up space for files already cached.

Spotlight

Windows Search and Spotlight on macOS can be used to search for files on remote storage in Integrated connect mode.

New Default

The Integrated connect mode is the default for new connections configured. Existing bookmarks retain the connect mode when an existing cache location is found.

Custom Versioning

2025-08-12T17:01:00+02:00

With Mountain Duck 5, a new storage-independent versioning option is introduced for protocols with no support for file versioning such as FTP/SFTP, WebDAV, and OpenStack Swift. Safeguard against potential file loss with custom versioning. Stash changes to a file in a versioned folder on the server.

The custom versioning option can be enabled in the bookmark configuration or by default in Preferences → Versions tab.

Use the context menu Info → Versions to retrieve the file history where previous versions can be previewed, deleted or restored. Alternatively manage previous versions stored in the folder named .duckversions adjacent to the file.

More information on the settings can be found in the documentation.

Mountain Duck 5 Public Beta

2025-07-14T14:10:00+02:00

Get a sneak peek at upcoming Mountain Duck 5. Features new Integrated connect mode using native APIs on Windows & macOS to integrate in the file explorer. No device driver installation or network mount required. The connect mode allows to sync files like OneDrive on Windows or iCloud Drive on macOS using the cloud storage provider of your choice. All major protocols are supported to connect to just about any server you want with SMB added as an additional option in version 5.

The new connect mode benefits from faster file write performance and file operations in general on par with operations on local disk. Local storage is managed by the operating system. The mount is not seen as a remote volume by applications but as a regular folder on disk and can be accessed when offline. You will find familiar user interface in Finder and Windows Explorer to select files to keep offline, remove cached data on disk or exclude from sync. An additional icon provided next to the filename is displayed indicating the synchronization status. Additionally, progress is shown when downloading or uploading a file with a progress bar over the file icon or circular progress indicator adjacent the filename. Windows Search and Spotlight on macOS can be used to search for files.

Choose Preferences → Update → Beta → Check for Update… in the Mountain Duck status bar menu to update. The build can be used with a validation registration key for version 4 while in beta.

Application blocked by Google

2024-08-18T18:39:00+02:00

This issue has been resolved as of September 11th with the OAuth App Verification completed including the paid CASA assessment.

To access Google Drive or Google Cloud Storage using Cyberduck or Mountain Duck we have registered an OAuth 2.0 Client ID with Google that is required to show users a consent screen to access files from these cloud storage services using the respective APIs.

Google recently blocked the consent screen and now shows the following error when trying to open a new connection:

This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.

We are aware of the problem and are currently working on getting the consent screen re-approved by Google.

No user data is collected or shared when you access your data in Google Drive or Google Cloud Storage using Cyberduck or Mountain duck. We do not transfer or disclose your information to third parties. Any data accessed is processed solely on your device.

As a workaround you can register your own Custom OAuth 2.0 Client ID for Google Cloud Storage and Google Drive and using with a custom connection profile instead.

Keep previous versions when editing files

2024-06-27T16:16:00+02:00

Cyberduck 9 adds a new custom file versioning feature for protocols with no native versioning support, such as FTP/SFTP and WebDAV.

The feature is added as a security measure to reduce the risk of file loss when editing changes. You can enable the option by default in the Editor tab in Preferences.

The versions can be previewed, deleted or restored in Edit → Info → Versions with the same user interface as when working with revisions from protocols with native versioning support such as a versioned bucket in S3.

Technically instead of overwriting files, previous versions are moved to a folder named .duckversions created adjacent to the edited file. The documentation has more details.

Connect to ownCloud Infinite Scale (oCIS) using OAuth

2024-04-02T09:12:00+02:00

ownCloud Infinite Scale is a user-centric, cloud-native, open source, file sharing and collaboration platform that offers infinite scalability and enables complete digital sovereignty.

ownCloud Infinite Scale uses federated authentication with Keycloak as the identity provider by default. To connect using Cyberduck or Mountain Duck.

We will provide sample steps to connect to ownCloud Infinite Scale (oCIS) using OAuth 2.0/OpenID Connect (OIDC). It requires the client registration in the identity provider in ownCloud and a custom connection profile for Cyberduck & Mountain Duck. To allow to test this without a custom deployment, the sample makes use of the public instance running at ocis.ocis-keycloak.latest.owncloud.works with the identity provider at keycloak.ocis-keycloak.latest.owncloud.works. You can login with the username “admin” and password “admin”. Note that these demo instances are wiped periodically and all data and configuration is temporarily available only.

Import client configuration

You will need to import a client configuration for Keycloak to allow OAuth authentications from Cyberduck & Mountain Duck. The configuration registers a OAuth Client ID with the redirect URIs x-cyberduck-action:oauth and x-mountainduck-action:oauth set to allow a seamless login integration.

Connection Profile

The connection profile defines the custom OAuth Client ID to be used to connect to ownCloud including the authorization and token URLs used for authentication with the Keycloak identity provider. The connection profile matching the above client registration is

Connect to S3 with web identity federation

2023-10-18T16:20:00+02:00

The latest versions of Cyberduck & Mountain Duck now allow to connect to S3 by authenticating with an OpenID Connect (OIDC) identity provider.

Connections to S3 with web identity federation use AWS Security Token Service (STS) API to obtain temporary security credentials to authenticate with S3.

With web identity federation, you don’t need to (…) manage your own user identities. Instead, users of your app can sign in using a well-known external OpenID Connect (OIDC)-compatible IdP. They can receive an authentication token, and then exchange that token for temporary security credentials in AWS that map to an IAM role with permissions to use the resources in your AWS account. Using an IdP helps you keep your AWS account secure, because you don’t users to have long-term security credentials.

Default connection profiles for Google and Azure

Default connection profiles are provided to use Google or Azure AD as an identity provider in conjunction with AWS.

These default profiles will prompt users for the Role ARN configured in AWS IAM referencing the trust relationship configured with the identity provider. Assigned by AWS this has a format similar to arn:aws:iam::930717317329:role/my-role-name.

Configuration in AWS IAM

Add an identity provider in IAM. Refer to the documentation from AWS.
Assign a role. The role is crucial as it contains both the trust relationship with the identity provider and permission policy:
The trust policy restricts access to users authenticated with a specific identity provider and allows to filter for specific users in the Condition statement with access to the JSON Web Token (JWT) claims that can be matched.
With the permission policy attached it limits access to a predefined set of buckets or keys.

Refer to the AWS documentation on Creating a role for web identity or OpenID Connect Federation.

The role that your application assumes must trust the identity provider that is associated with the identity token. In other words, the identity provider must be specified in the role’s trust policy. The call to AssumeRoleWithWebIdentity should include the ARN of the role that is specific to the provider through which the user signed in.

Custom Integration

We have made available documentation to write your own connection profile for different combinations of S3/STS and identity provider such as MinIO S3 authenticating with MinIO STS and Keycloak (OIDC).

Documentation

Refer to our S3 documentation.

SMB Protocol Support

2023-10-18T15:14:00+02:00

SMB (Server Message Block) is used to access Windows File Shares or a Samba Linux Server. Cyberduck 8.7.0 adds support to access SMB shares as an light-weight, performant alternative to built-in support in macOS and Windows. Support in Mountain Duck is forthcoming in version 5.

Connecting to SMB

To connect to your SMB (formerly known as CIFS (Common Internet File System) server such as a NAS (Network Attached Storage) using NTLM authentication, select SMB (Server Message Block) in Open Connection or the Bookmark configuration. The default domain name is set to “WORKGROUP” and can be changed to meet the username format requirement depending on the server setup.

SMB Share

You will provided with a list of available shares from the server or alternatively if not supported prompted to input the share name manually. Specify the share name as a Path in the bookmark to avoid connect to a single share.

Up-to-date information about SMB interoperability can be found in out documentation.

Alternative to the official Dropbox client

2023-03-07T13:32:00+01:00

Dropbox recently adopted the File Provider API available on macOS to be used as the exclusive way to synchronize files with their own app. The most prominent change from a user perspective is the limitation to store all synchronized files in ~/Library/CloudStorage as required by the File Provider API. Many users with large data sets preferred to set a custom location on an external disk previously which is no longer an option.

Use Mountain Duck instead of the official Dropbox client

Mountain Duck is a viable alternative to the official Dropbox client. It allows to connect to and synchronize your files in Dropbox without any additional bloat. In Mountain Duck Preferences, you can change your cache location to a different folder or even to an external drive.

Connecting to Dropbox

Mounting your Dropbox in Finder is straight forward using Mountain Duck:

Select Open Connection within the Mountain Duck dropdown menu
A new bookmark window will pop up
Select Dropbox from the protocol section on the top and choose Connect
Your web browser will open leading you through the authentication and authorization flow

Once successfully connected, your files from Dropbox will open in Finder. To connect to a single folder instead of the root, add a path to your bookmark configuration. Without adding a Path to the bookmark configuration, you will be connected to the root of your Dropbox.

Connect to multiple accounts

Connect to and work with multiple Dropbox accounts simultaneously. Repeat the above steps to connect to an additional Dropbox account you may have access. Open a new bookmark and login to the other Dropbox account in your web browser when authorizing access for Mountain Duck.

Use Cyberduck to retrieve files from Dropbox without syncing

Alternatively, use Cyberduck to browse your Dropbox without syncing the files to your computer.

Boxcryptor Alternative

2023-01-03T16:20:00+01:00

Boxcryptor has been acquired by Dropbox and will terminate free accounts as of January 31, 2023. Till then, all users have to look for an alternative. It is not clear how customers with existing contracts are served in the future and no new accounts are accepted. So why not use Mountain Duck with support for the Cryptomator vault format independent from a single provider?

Smart Synchronization

Mountain Duck allows you to mount multiple cloud storages and servers as network drives on macOS and Windows using Smart Synchronization for offline access. Use the built-in, fully interoperable support for Cryptomator vaults to encrypt your sensitive data in password-protected vaults with end-to-end and zero-knowledge encryption. You do not need to have the Cryptomator apps installed but can access the same vault using Cryptomator for iOS for example.

Interoperable

Cryptomator is free and open-source software with no security by obscurity, no hidden backdoors from third parties, no need to trust anyone except yourself. No online services, no subscriptions, no accounts.

Migration

Follow these steps to migrate documents currently in Boxcryptor to a Cryptomator vault accessible through Mountain Duck:

Decrypt all existing files in Boxcryptor by following Off-Migration Guide: Decrypt all Boxcryptor encrypted files.
Download and install Mountain Duck for macOS or Windows.
Create a new connection to any service provider supporting one of the many available protocols including S3, Dropbox, OneDrive & Google Drive or any WebDAV and SFTP compatible storage.
Create a new vault in on your preferred storage.

Documentation

Follow our documentation for step-by-step instructions to create a new vault or access an existing vault stored on your preferred cloud storage (including Dropbox).

macOS Ventura

2022-11-02T18:40:00+01:00

Both Cyberduck and Mountain Duck are fully compatible with macOS Ventura.

Local Cache Size Limitation

2022-06-29T13:30:00+02:00

Mountain Duck 4.12 introduces new settings to allow cache management — a top requested feature.

In Smart Synchronization connect mode all files you work with (e.g. open, save, upload or explicitly choose to keep offline) are saved in the local cache to shorten access times and to make them editable when offline. Depending on the size of your files, this might eat up your local disk space. This can be problematic in particular for computers with a small SSD disk. The new cache management feature gives you the ability to define a retention time for files and to limit the size of the cache in general. Both settings can be enabled either separately or in combination.

The first option defines the retention time in days after which a file is purged from the cache when it was not accessed during this period. The size option is a soft limit that does apply on a bookmark basis and excludes files marked to be kept offline by the user. In any case, older files are always purged first.

View and Retrieve Previous File Versions

2022-06-29T11:42:00+02:00

Cyberduck 8.4 and Mountain Duck 4.12 revamp support to view and retrieve previous versions. Instead of the context menu, previous versions are now listed into the Versions tab of the Info window.

Using the buttons in the lower-left corner, you can perform different actions on the selected version:

Revert to this version
Delete the version permanently
View the version using QuickLook on macOS or open this version in the default editor application on Windows.

The versioning feature is now available for Amazon S3, Backblaze B2, Dropbox, Google Drive, Google Cloud Storage, Microsoft OneDrive, and Microsoft Sharepoint connections. You can find full interoperability information in the documentation available.

Customizable Notifications

2022-06-29T11:23:00+02:00

Mountain Duck 4.12 introduces a new Notifications tab in Preferences that allows customizing the notifications to be displayed. In particular it allows fine tuning which notifications to receive when file changes are detected on the server and background synchronization activity.

Box

2021-12-23T15:49:00+01:00

Cyberduck 8.2 and Mountain Duck 4.10.0 introduce support for accessing Box not only through their FTP or WebDAV gateway but using the native Box API. This should not only improve performance but additionally allow enabling two-factor authentication (2FA) for the account. The new implementation allows to create download and upload shares of files or folders for people who are not Box users by using File → Share…in Cybereduck or Create Download Share or Create Upload Share from the Mountain Duck context menu respectively.

Download Mountain Duck as an alternative to Box Drive.

🏠 Moving to GitHub

2021-11-30T15:06:00+01:00

We previously only had mirror repository for Cyberduck on GitHub and managed pull requests for changes on our own Git server and mirrored all changes to a SVN repository which was used to display a timeline of changes in Trac.

We are now using the repository on GitHub as the primary source root and accept pull requests at the same place. Previous milestone history has been preserved. This will make contributions more straightforward and simplify the development setup for many.

Issues

We now use Github as well to manage all issues containing bug reports or feature requests. We have migrated all previous 11919 tickets opened in Trac since 2005 to GitHub.

Documentation

Additionally we will also retire the current documentation in the Wiki and move it to docs.cyberduck.io. Contributions to the documentation written in Markdown are welcome can be made by opening a pull request.

Embracing Apple silicon

2021-11-25T16:00:00+01:00

The latest versions of Cyberduck and Mountain Duck now run natively on Apple M1 hardware. Thus we are again shipping a universal binary on macOS since dropping support for PPC and Intel 32-bit (i386) in version 4.4 released in October 2013.

This was made possible by the work in Rococoa, JNA and libffi.

Connection Profiles

2021-10-27T10:26:00+02:00

Cyberduck 8 and Mountain Duck 4.8 introduce a new Profiles preferences tab that allows to install additional connection profiles on demand. This makes it much easier to connect to various hosting and cloud storage service providers without the need to lookup connection details other than credentials.

Cyberduck Preferences (Windows)

Usage

You can either scroll through the list of profiles or use the Search function. To install a connection profile simply enable the corresponding checkbox. The profile will be downloaded and saved in the “Profiles” folder of the application support directory right away. Since Mountain Duck and Cyberduck refer to the same application support directory the connection profiles are shared between both applications. Disabling the checkbox deactivates the connection profile for the currently used application.

Providers

Service providers that define connection profiles and open an issue to request the connection profile to be added to the default repository.

macOS Monterey

2021-10-25T15:41:00+02:00

As the latest version of macOS now numbered 12 will arrive later today both Cyberduck and Mountain Duck are fully compatible.

ARM support for Cyberduck CLI

2021-01-18T18:03:00+01:00

Cyberduck CLI is now available for the growing ARM ecosystem. Run the universal file transfer tool on AWS EC2 A1 instance types or Raspberry Pis for example. Both DEB and RPM package types are available in 32bit and 64bit for ARM. The regular installation instructions apply.

Search bookmarks

2021-01-12T21:29:00+01:00

Mountain Duck 4 introduced labels to assign to bookmarks to allow grouping in folders in the status bar and system tray menu. To further ease the lookup of bookmarks for power users with many connections we have now added a search field in the menu in version 4.4 as known from the Cyberduck browser window.

Connecting to different Sharepoint libraries

2021-01-12T12:51:00+01:00

Cyberduck 7.8 and Mountain Duck 4.4 improve support for Microsoft Sharepoint connections. The Microsoft SharePoint Site connection profile now allows to connect to specific sites. The regular Microsoft SharePoint connection profile adds support to browse different libraries. Refer to our extended documentation for both OneDrive and SharePoint.

Big Sur

2020-11-10T13:01:00+01:00

We have made some adjustments in version 7.7 of Cyberduck to support the new window appearance introduced in macOS 11. Switching between bookmarks and browser view is now always visible in the toolbar.

The bookmark proxy icon is now displayed inline with the other toolbar controls including the bookmark nickname replacing the previous window title.

Additionally the input field to search for bookmarks or files is now located in the toolbar and treated accordingly.

When horizontal space is limited, the toolbar can display the Search button in place of the search bar. When people click the Search button, the bar expands; when they click elsewhere in the window, the search bar collapses and the toolbar displays the button again.

Restore from Glacier

2020-09-10T16:28:00+02:00

We have made available a feature in Cyberduck 7.6 and later to restore files from Glacier storage class in S3. You can temporarily restore files from Glacier using File → Restore for files with the storage class set to Glacier. The file will be restored using standard retrieval and expire in 2 days after retrieval. Restoring takes some time and attempting to download an item not yet restored will lead to an error *The operation is not valid for the object’s storage class. *

Mountain Duck 4

2020-06-18T08:43:00+02:00

We are thrilled to announce the release of Mountain Duck 4 – the premier choice to mount server and cloud storage as a disk in Finder on macOS and the File Explorer on Windows.

File History with recent changes

Version 4 adds a file history with a detailed view of transfers in progress and history of recently edited files on your computer and on the server. Users can select an item to quickly reveal the changed file in the file explorer.

Labels for Bookmarks

Assigning labels to bookmarks allows grouping bookmarks in folders in the menu further enhancing the unobtrusive user interface.

Features for Teams

Locking files prevents conflicting edits from others while editing a document. Support has been introduced locking files when connecting to a WebDAV server. Additionally, locking for protocols with no native lock support using lock owner files has been implemented to allow alerts for concurrent edits in Microsoft Office.

Also when working with versioned buckets in S3, users can open and revert previous versions of files.

Upgrade

Please upgrade your license before updating. Existing customers get an upgrade discount between 40% to 100% depending on the date of purchase.

File History in Mountain Duck 4

2020-06-17T19:24:00+02:00

Mountain Duck 4 adds a file history feature which allows you to see which files were recently edited by you or someone else on the server and which files are currently transferred or pending synchronization.

Synchronization Progress

The sync progress area of the file history section shows the files that currently get synchronized and the files that will get synchronized after the current synchronization process. There are different synchronization states that can get displayed within that area: idle, active synchronization process, and prepare for synchronization.

Shown for active synchronization processes are transfer rate, remaining data, and already transferred data. If Mountain Duck synchronizes files in a badge, the file state might differ to the state within the file browser. The sync progress display limit is five entries.

Clicking on a file in the sync progress Mountain Duck reveals it in Finder or File Explorer on Windows.

Recently used Files

The second key section of the file history feature is the Recent Files area in which you can see the last 20 items that Mountain Duck uses for one of the following processes: delete, create, upload, and download. Also, a file may show up with an error state indicating an issue while synchronizing. Further details are available through the Finder or Explorer extension sync options menu item.

Clicking on a file in the Recent Files section Mountain Duck reveals it in Finder or File Explorer on Windows. You can clear out all entries of the list by clicking on the Clear Menu button at the end of the file history menu.

Cyberduck 7

2019-06-05T08:00:00+02:00

With Cyberduck 7 we introduce the possibility of a multi-segmented download. Multi-Segmented downloads offer the functionality to download one file over several connections. This has the advantage that some files can be downloaded faster and the download process is less error-prone.

In previous versions of Cyberduck, there was only the possibility to run downloads over a single serial connection, the multisegmented download feature multiplies the connections making a parallel download process possible. The following diagram visualizes the two types of download described.

You can expect at least a doubled download speed if you use the multisegment download functionality. Some additional time is required to concatenate the downloaded segments after the download itself is complete. We have collected the following data in download tests with downloads from Amazon S3 and a Minio server running locally.


	AWS EC2¹	Local System²
Regular Download	20 MByte/s	200 Mbyte/s
Segmented Download	40 Mbyte/s	1 GByte/s

¹ AWS EC2: T2.Medium against a regular S3 endpoint

² Local Minio S3 Server feeding data from local NVMe-PCIe-SSD

The described feature can be turned on or off in Preferences → Transfers → General → Downloads.

Refer to the full changelog for many more enhancements and bug fixes.

Mountain Duck 3

2019-04-30T10:46:00+02:00

Work Offline with Smart Synchronization

Version 3 adds a smart synchronization feature to add offline support. Files are synchronized to the local disk when opened to allow offline usage and changes are uploaded in the background as soon as a connection is available. Dropbox like experience with your preferred on-premise enterprise storage or cloud storage. With the additional option to choose which files and folders are available for offline use. Other files are visible but only stored as placeholders. These do not take up disk space on the computer and are downloaded on demand only.

Edit files Offline and upload changes when connectivity to remote server is restored.

Badge Icons

Badge icons in the Finder and Windows Explorer indicate the sync status of files – easily assess if the file is only available when online or is synced to your computer for offline editing. Synchronization with the remote storage is paused and resumed automatically depending on your network connection. The application icon in the system tray animates when a background transfer is currently in progress.

Upgrade

Mountain Duck 3 is a paid upgrade. Existing customers get an upgrade discount between 40% and 100% depending on the date of purchase. Please upgrade your license before updating.

Access NextCloud from your desktop

2019-04-23T20:00:00+02:00

Update. Cyberduck 7.0.1 and Mountain Duck 3.0.3 now include a connection profile for Nextcloud & ownCloud by default allowing a more straightforward setup. You can now also select files to create a public share link.

You are looking for a way to connect to your NextCloud or OwnCloud server without loosing any hard disk space on your computer? Mountain Duck mounts your server storage as a network drive in which you can transfer and edit files. The following describes the connection process to NextCloud with a Mountain Duck Bookmark step-by-step.

Connect to your NextCloud or OwnCloud instance in your web browser and log in.
Click on the option Settings in the lower left of the screen and copy the displayed WebDAV address.

Start Mountain Duck, click on the icon in the tray area or status bar and choose the option New Bookmark.
Paste the previous copied WebDAV address into the server field and press tab. After that, the bookmark should have chosen WebDAV (HTTPS) on its own and should have split the WebDAV address into two parts – the server address and the default path.

Type your Username into the corresponding field and press Connect.

Enter your password in the login prompt displayed and choose Login.

The login and connection process opens automatically a Finder (macOS) or File Explorer (Windows) window with the network drive selected – ready to use.

Mountain Duck 3 as an alternative to the Dropbox client application

2019-04-23T20:00:00+02:00

Mountain Duck 3, combined with any cloud storage, is a viable, more secure solution to synchronize access to documents on multiple computers and users. With Mountain Duck 3 you have the ability to make files and folders accessible for offline usage selectively. This has the advantage that not all data is kept on your local drive for offline usage compared to clients like Dropbox and Google Drive. Additionally, you can apply this principle to all of your bookmarks and not only on the already mentioned cloud storage provider.

Keep files selectively offline

Open Mountain Duck and connect to the desired Bookmark (We’ll use Dropbox in our example).
Navigate to the file or folder that you want to keep on the disk for offline usage.
Right-click on the desired file or folder and choose Sync Options → Keep Offline on Local Disk in the context menu. If you are using macOS you have to activate the Finder Extension in order to reach the described option.

Wait until the file is successfully synchronized. The chosen file or folder should show the following badge icon.

Now you can access the file when you aren’t connected to the Internet. All file changes will be synchronised as soon as connectivity to the remote storage is restored.

Connect to multiple accounts

You can mount multiple accounts at the same time if you have different Dropbox accounts. Create a new bookmark for every account and run through the OAuth flow. Make sure to log out of the Dropbox website prior setting up a new bookmark.

Sharing Large Files

2019-01-30T20:00:00+01:00

You want to grant one or several people temporary access to large files? Email is not an option and providers offering a web interface are costly, limit the file size or tend to be unreliable. Cyberduck or Mountain Duck in combination with cloud storage providers allows you to share files without relying on a third-party website.

Auto Expiring Links

With Cyberduck or Mountain Duck and those cloud storage providers, you can share links with third parties that expire after an hour, days or months. Between the protocols, the expiration time of the shared links may vary. Contrary to other solutions there is no restrictions on bandwidth or the number of downloads.

Supported Providers

In the following section, you will find a short guide on how to share large files with Amazon S3, Microsoft Azure, Dropbox or OpenStack Swift cloud storage providers.

Step by Step

Open Cyberduck or Mountain Duck and connect to your Amazon S3, Microsoft Azure, Dropbox or OpenStack Swift bookmark.
Navigate to or upload the file you want to share
Right-click on the file, choose the option Copy URL in the context menu and click on the Pre-Signed URL (within Dropbox it is named Temporary URL) with the wanted expiration time. In Cyberduck the same option is available in Edit → Copy URL→ Signed URL. Share the link with anyone you want to give access to.

Update See also our documentation on sharing options for different storage service providers.

Accessing OneDrive & Sharepoint

2019-01-16T08:00:00+01:00

The number of different possible options for cloud storage provided by services available from Microsoft Office 365 is confusing and merits some further ado. There are two services available from Microsoft – OneDrive and SharePoint – which are hidden in a diversity of different packages. SharePoint is a cloud storage service which is only integrated in business packages while OneDrive is existing for personal and business usages. Every person who has a Microsoft Account does have access to the personal version of OneDrive. You can detect if you have a personal or business profile by looking at the email address. If you have a business profile the email address contains onmicrosoft.com.

In the following chart an overview of the most common business profile packages and whether the packages contain OneDrive, SharePoint or both is shown.

[TABLE]

Cyberduck and Mountain Duck support OneDrive in personal and business edition as well as SharePoint through the default bundled connection profiles Microsoft OneDrive and Microsoft SharePoint. It doesn’t make any difference if you are using OneDrive personal or business there is only one profile that works for both. To connect to OneDrive or SharePoint with Cyberduck or Mountain Duck you have to create a corresponding bookmark which will connect to the services via Microsoft Graph.

Connecting to OneDrive Personal and Business

Click on “New Bookmark” if you are using Mountain Duck or on the “+” symbol in the browser window if you are using Cyberduck to create a new bookmark.
Choose the profile Microsoft OneDrive.
Type in the Username field your account email address and connect to the bookmark.

A window appears and prompts for an authentication code. Alongside with the authentication code prompt, a web browser window should open with the login page of Microsoft. Log into your account in the web browser window and copy the afterward appearing authentication code into the field in the authentication prompt window.

If you are using Cyberduck a browser window will appear. If you are using Mountain Duck Windows Explorer or Finder are opened revealing your OneDrive.

Connecting to SharePoint

Click on “New Bookmark” if you using Mountain Duck or on the “+” symbol in the browser window if you using Cyberduck to create a new bookmark.
Choose the previously installed profile Microsoft Sharepoint Document Library or the bundled profile Microsoft SharePoint.
Log in with your *.onmicrosoft.com account to login.microsoftonline.com to connect to your SharePoint document library. If you want to connect to SharePoint online you have to use your OneDrive personal account.

More information can be found in the Help Wiki for both OneDrive and Sharepoint.

🦆 Mountain Duck 3 – Public Beta

2018-11-17T14:17:00+01:00

We are thrilled to release a public beta of upcoming Mountain Duck 3. The new version is a major milestone in our development timeline. Bridging the gap between online only access with no use of local disk space in Mountain Duck 2 and the new smart synchronization feature in Mountain Duck 3 with much improved performance accessing files is the main focus.

Think of it like Dropbox for any server and cloud storage but with the option to choose which files and folders are available for offline use while others do not take up disk space on your computer.

Smart Synchronization for Offline Usage

The smart synchronization feature allows to make files available offline. You can also choose to make explicitly all or only selected files and folders available for offline use. Changes to files are saved in a local cache first and uploaded in the background as soon as a connection is available.

Badge icons in the Finder and Windows Explorer indicate the status of files – which indicates if the file is only available when online or is synced to your computer for offline editing. Regardless of the status, you will always see all your files!

Synchronization with the remote storage is paused and resumed automatically depending on your network connection but can also be paused by the user manually. You will see a blinking duck icon in your system tray when a background transfer is currently in progress.

Documentation

Updated documentation for the new smart synchronization feature can be found in our wiki.

Encrypt your Dropbox

2018-11-15T21:04:00+01:00

Mountain Duck and Cyberduck allow Cryptomator client-side encryption of your data which is missing in Dropbox and all other popular cloud storage solutions. You will find a description of how to use Cryptomator Vaults in Dropbox and access your documents from your computer and mobile in the following sections.

Encrypt your data with Mountain Duck and Cyberduck

Connect to your bookmark and navigate to the location where you want to store your secured data.
Right-click on white space and choose New Encrypted Vault in the context menu.

As described in the appearing window enter a name for your encrypted folder. Afterward, choose a password and confirm it by retyping it in the last field.

Double-click on your newly created Vault and unlock it by typing the password into the corresponding field.

The Vault opens. Now you can create or copy the documents you want to secure into the Vault to encrypt them.

Access your encrypted data with the Cryptomator app on your mobile.

Install the Cryptomator App on your mobile (IOS, Android).
Tab on the plus symbol and choose the option Add existing vault.
To open the previously created Cryptomator Vault choose the cloud service Dropbox, log into your account and navigate to the Vault.
Open the Vault folder and select the masterkey file which is named masterkey.cryptomator. After that, the app should show automatically the landing page of the Cryptomator app with the previously selected Vault pinned.
Tab on the pinned Vault and type the password into the corresponding field. The Vault should open right after you have unlocked it with the password and you have access to your secured data.

This process does not only work with Dropbox but with any other connection supported in Cyberduck and Mountain Duck. You can find more information on Cryptomator support in our wiki.

Dark Mode

2018-09-21T13:45:00+02:00

Version 6.8 is now available with support for dark mode on macOS Mojave.

Connecting using AssumeRole from AWS Security Token Service (STS)

2018-08-07T11:54:00+02:00

Instead of providing Access Key ID and Secret Access Key, authenticate using temporary credentials from AWS Security Token Service (STS) with optional Multi-Factor Authentication (MFA), making Cyberduck and Mountain Duck more friendly to enterprise deployments. You will need to install the custom connection profile S3 (Credentials from AWS Security Token Service) available from our website.

Our implementation to obtain temporary credentials is interoperable with standard AWS CLI configuration in ~/.aws/credentials. Refer to our wiki for documentation.

Support for Office 365 Deutschland

2018-08-07T11:39:00+02:00

Skip writing temporary application files to remote volume

2017-11-27T20:47:00+01:00

We have taken a big leap forward in performance working on remote volumes with Mountain Duck from applications that read and write temporary files when saving documents. Extended attributes and temporary files from applications are no longer saved on the remote volume but in a local temporary cache only.

This change in version 2.1 significantly speeds up read and write operations from applications.

Google Team Drives

2017-11-14T15:18:00+01:00

We have added support for Google Team Drives in both Cyberduck 6.3 and and Mountain Duck 2.2.

Google Team Drives are shared spaces where teams can easily store, search, and access their files. Unlike files in My Drive, files in Team Drive belong to the team instead of an individual. Even if members leave, the files stay exactly where they are so your team can continue to share information and get work done. Team Drives is available on G Suite Enterprise, G Suite Business, or G Suite for Education editions.
