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.
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.

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.
