I used Defraggler for years on my old PC with Windows XP-Pro and a 40 gb hard drive with much success. I have a relatively new desktop PC with Windows 8.1 (all updates) and a 1 tb hard drive. I also have Norton 360, which does cleanup and tuneup tasks automatically in the background, including defragging. I had been told that I don't need to defrag manually. But I decided to do a Defraggler analysis, and it told me that I had 25% fragmentation, which seems awfully high to me. So, I ran Defraggler. It said it would take more than a day, but I let it run overnight and it was done in the morning. Now, it says that the fragmentation is 30%, with 3164 fragmented files and 16,776 fragments!!! What is going on? Does defraggler not work correctly in Windows 8.1? What can I do now to fix this?
