I am on a Celeron 300a with 160 MB of RAM, and using a 13 gig 7200rpm ATA66 hard drive. My hard drive has about 3 gigs free. I am in the process of sorting and backing up the hard drive onto cdr's, but after accessing a few folders and checking their contents in explorer it begins to drag. It can take up to 30 sec's to see the contents of a folder, or rename it. The hard drive is freshly defragged, and scanned. Is this a virtual memory thing? I even get this result after shutting down all background programs.
