I'm trying to connect to an HTTPS WebDAV folder on Windows 7. I go to a "Computer" Explorer window, right click, and click "Add a Network Location." I follow the prompts and get "The folder you entered does not appear to be valid. Please choose another." It works fine on Windows XP. How do I make this work?
Instead of going through the GUI it said you should go to a command prompt and type in a command similar to this one:
net use * https://webdav.example.com:port/folder
It prompted me for a username and password and then mapped the drive.
I was able to access my files this way. Hope it works for you.
