Ok, so I just installed 64 Bit Vista on my Raptor 300 Gig harddrive, I've only installed a handful of programs, Microsoft Office, WoW, and some instant messengers. For some reason I have already used 100 gigs? I don't see how this is possible at all, I looked at my local disk C, all of the folders and I should, at MOST, only have used about 40 gigs of space. Any idea on if there is a program that lists every file on a drive and the size of them? Or anything that can give me a similiar effect?
