Defragging;- I get conflicting opinions about this, some say that you should/must do it on a regular basis, then you get the extreme;- people that say that they never defrag. My hard drive is always about 25% full [25% used, if that's the correct terminology] I did do it once on a "friend's" advice, & soon after it had to go into a workshop; freezing often, oversized, thus unusable icons [overflowing the screen] the only thing that could be done, I was told, was to re-load Windows & as I hadn't the Windows Professional disc, [another "helpful" friend loaded THAT for me] Windows Home, my original system, was re-loaded, & things went back to normal, or as near normal as my PC ever gets. So, to sum up,what's the general consensus on de-fragging? & did the above system change possibly cause mayhem when I did de-frag? I am now nervous about doing it, although I am told that it "will speed everything up" in view of my 25% used, would that be true in my case?
