I have Windows xp home edition. When I open the defrag window and click anayze, a window pops up and says you should defragment this volumn. After defragging, when I check the window again it still says you should defragment this volumn. In other words, my computer will not satisfactorally defrag. I have 58% freespace still available. My most fragmented file is \WINDOWS\Microsoft.NET\Framework\v3.5\microsoft.NETFramework. It has 222,960 fragments and a file size of 17.77 GB. Is this something I can delete and redownload or am I stuck?
