It was a while ago now but I think this what I had done to move the folder:

To make the move, open C:\Users, double-click your user profile folder, and then right-click any of the default subfolders there and click Properties.
On the Location tab, click Move, and then select the new location for that folder. (If you enter a path that doesn't exist, Windows will offer to create it for you.)
Click OK or Apply and you'll see a prompt asking whether you want to move files from the existing folder to the new location. In general, you should say yes to this request.
