myCloud Desktop enables you to generate a share link to an already synchronised file directly from the Desktop Client.
The link will then be copied directly to your clipboard. You can then insert this somewhere such as in an email:
Windows: Right click [Symbol] Paste or CTRL+V
MacOS: Command-V (⌘V) or right click [Symbol] Paste (Right click must be activated)
The recipient of the link can download the file without needing a myCloud account.
The file will be available through the link until you stop sharing permission. In myCloud under “Shared” you can view all files currently being shared.
