I recently (1 week) moved from Vista to the RC with a clean install that was supposed to format my laptops hard drive. Now when I view my C: drive's properties it says 168gb used and 33gb free space. I have a couple word docs and maybe 1gb of music that I've actually put on since I installed win7 so whats doing this? How can I get win7 to show my true used space and/or clean the hard drive without completely reinstalling? I used the partition manager to check and all the space in is my main C: partition so thats not the issue, any ideas?
