Hey thanks TheOdds! That definitely appears to be a darned good explanation of what's been going on. And the 'logging out/in' bit also seems to have a bearing in my case. Perhaps. In that ever since I deleted my TIF and things went pear-shaped, every time I've tried to delete any of these new folders from my Temp folder I am made to log out and log in again for the deletions to take effect. Supposedly take effect because more often than not, but not always, the deleted folders are still there when I log back in. My point is, until this happened I've never ever been logged out and made to log back in after deleting stuff, and at the most been told to restart. But not log out and in again. This is completely new to me. Could it be a sign that my security settings have been changed or something? I was in fact, a few minutes ago, successful in moving my Content.ie5 folders back to their original place and deleting the newly made TIF and Cookies folder from the Temp folder. Even though they both contained index.dat files. Maybe this was because XP took a couple of days to 'right' itself. Now I'm just left with a redundant History folder (containing another History folder containing several MSHIST*** files and all containing their own index.dat files) sitting in my Temp folder. This still doesn't want to budge. I can live with that. I don't think I'll use CCleaner to delete my TIF again though.
