I have question about fragmentation in general. I know how fragmentation works and why it happens, but I can't explain this situation:
I have partition where I store all my movies, music, and nothing else. So most of the files are about 700MB+. I'm using Defragger, and it says I have 0% fragmentation on mentioned partition. Good so far. Yet, after few days some of these 700MB+ files become fragmented, even when I didn't open these files. It looks like the files are fragmenting itself without any reason. Or maybe there's something that I don't know?
My question is: why this happen? And what to do to prevent this unreasonable fragmentation.
Hi, I don't know off hand what could be causing it but if there are red blocks showing, click them and see what they are; that might give you some clues.
I was also thinking it might be Windows Indexing Service or Google Desktop, if you have either of those enabled, but I don't think they do anything that would cause fragging, but I'm no expert so it might be worth looking into.
After defragmentation, there's no red blocks. Yet, few days later they appear, even if the files that are now in red blocks wasn't used since defragmentation.
I don't use Google Desktop, but I follow your advice and turned Windows Indexing Service off. We'll se If that helps.
