Rather than drag another thread off topic.... Don't keep me in suspense! It's not just miss puttees that has the problem, I have too. (But her hard drive is filled with junk, mine isn't) I'm currently only 32% through a defrag after running for over 6 hours - C drive 80% full, D drive 5% full and "partition" is a mystery word, so I daren't fiddle with that. Total hard drive is 57GB, with C: =33GB, D: = 22GB (though it's described as a 60GB disk - I thought computers were supposed to be good at maths!) AV scans also take ages. I'd estimate that half the content of the C drive comprises essential programs while the other half has files that can be ditched elsewhere eventually but need to take up disk space for a couple of months. Needing space on the hard drive is my cue to be a good boy and put the unnecessary stuff onto a removable hard drive or DVD depending on the likelihood that it will need to be brought back. (Boss would have a fit if I downloaded all my stuff onto the company's servers - which would be the sensible move - as I generate more GB than most of the rest of the firm). So any tips to cut down the time of various scans would be helpful as these slow down some of the heavier programs that I use. PS RAM is 512MB, which seems to be plenty other than when scans are running, so unless increasing memory will provide additional benefits, I'm not keen to fork out for something that has a workround.
