myCloud Desktop allows you to generate a share-link on an already synchronized file directly from the desktop client.
The link will be copied directly to the clipboard. You can, for example, simply insert it in an email message:
Windows: right-click-paste OR CTRL-V
MacOS: Command-V (⌘v) OR right-click-paste (right-click must be enabled)
The recipient of the link can download the file without having a myCloud account him/herself.
The file remains available at the link until you cancel the release.
In myCloud, you can view all existing shares under "Shared-Files"
