A list of 'FOUND' files has appeared on the C drive. I tried to delete one and a message popped up saying that they were temporary files containing fragments essential for the operating system and other programs. I've never seen anything like them before in the year that I've owned this computer and as temp files I wouldn't have thought that they were very important. Can anybody explain exactly what they are and whether Windows is doing its usual trick of trying to preserve something for its own obscure reasons.
crx1600 thanks for the observation, my FOUND files are in folders too. I had forgotten because I run a dual boot system in which only the WIN98 OS accesses the net and all the important stuff is on another hard drive running XP away from internet nasties, so when I posted the thread I couldn't recall all the details.
There were three folders dating from Feb this year one of which was 2.84 GB in size. On the grounds that no OS should produce of its own accord anything temporary without explanation or information, I've taken the bull by the horns and deleted all three folders ignoring the advice given by the pop up dialogue boxes that the folders were important. They've probably got spyware in them placed there by Microsoft! I'll let you know if my XP OS gives up the ghost, but I don't think it will, I think there are huge chunks of MS's OS's that don't actually do anything much and deserve to be deleted anyway.
