Ah ok, thanks! So my files will be kept but my programs must be reinstalled. No big deal. Although I will have to re-download (legally) the 6gb installation file for Adobe Creative Suite! Ahh! And MS Office too for that matter
But ok I decided I will partition off 40gb, now I'm just waiting for the Windows Backup to finish moving my stuff to my external first (it's taking hours and isn't even half done!) because I feel like it's probably not a good idea to do the partition while it's trying to copy all my files over. I think I'm going to go ahead and install Windows 7 once that is done though, so hopefully my computer doesnt freak out!
