Hi
I'd like to point out that moving your default Doucment, Pictures, Music folder etc to another drive doesn't save you space on your C:\ drive, because the files aren't really in those folders.
The Libraries folders are links to the real files which are usually stored in your C:\Users folder someplace.
You can make new Library folders that are linked to other locations but the default folders are stored in Users.
If you want to move those files someplace else you need to go to where they are stored and move the actual files to new folders on another drive.
Here you can see my Libraries folder on the Left, and on the Right the actual location of the files in the Users folder.
