I have been trying to use the Disk Cleanup program that comes with Windows XP to clean up my system, but it doesn't seem to be working properly. I let it run for awhile last night, and an hour later I checked up on it and it was still on the first step (compressing files). There are three green bars on the status line and its been stuck like that. I am currently trying again and it has been running for about 20 minutes, with still no luck. Does anyone have any advice on how to correct this problem? Thanks!
