The WebDav function is available exclusively for our myCloud Pro customers.
WebDav establishes a direct connection to your myCloud account via the Internet. This will display the contents of the file area of your myCloud account directly in the File Explorer (Windows), Finder (macOS), where the existing files can be opened and edited directly.
There are also a variety of Mac, Windows and Smartphone applications that can connect directly to myCloud using the WebDav protocol.
