Hello I've had Vista installed for about 3 weeks now at least if not more. For some reason the Hard Disk Quota is reading 53.8 GB. I did a check on every single folder on my computer to see what is taking up so much. The Largest Folder Sizes are about 9 Gigs for the C:\Windows Folder and 1.8 Gigs for Music and 1 Gig for Pictures. Everything else is under that. I didn't do a fresh install (I know I know big mistake but the Vista Upgrade CD was asking for my RAID Drivers even though I don't have the CD for that). I can't seem to figure out what could be taking up so much! I tried disk defragment that brought it up to 62 but then it dropped back down to 53.8 after it was done. Am I better off backing up everything on my computer and just do a fresh install with the upgrade DVD? I own and Alienware m5700 laptop and I wouldn't even know how to get the Raid Drivers.
