So i've done drive mapping over a network before, but i'm trying to do something different.

My hard drives getting full so i got another drive, and someone told me that i could map my directories to the other drive but when i tried everything worked out fine except for my appdata file, for some reason i couldn't map that and so it messed up all my shortcuts and desktop (eventho i was able to map my desktop)

So can anyone help me on this so i can get is right?

What i really want is Win 7 alone, on my primary drive and everything else from installs to pics on the secondary drive.
