Hi I have been using defraggler for some time and I've been finding that even when I defrag with out even using any files on the computer the fragmentation only increases or just barely decreases. it now says that fragmentation is 55%.I used Auslogics DiskDefrag for comparison which only gives a reading of 4% fragmentation for the same main hard drive on my desktop. I'm running windows 7. Any suggestions as to why this occurs?
