I use Disk Defragmenter that came with my PC and I use it one or two times on weekends only, but it seems the more I use it the more my disk get's fragmented. A few weeks ago it was 1/4 fragmented, now it's getting more than half, I have a small HDD so I hardly install anything and if it is it's small games or pictures and my games are slowing down by the day. Every time the defragmenting opperation is complete I get a message saying something like "Not everything could be defragmented". I was wondering if somebody knows a good trusted free disk defragmenter I could you instead? P.S. I always check for Windows Updates nearly every day and I update my drivers a lot too so I don't know what could be causing this. P.S.S. I also use CCleaner to Clean my registry.
