This is a fairly good defragmenter but it never seems satisfied, by that I mean if you analyze your disk after you defrag, it still shows fragmented files. Third run with optimization and finally no fragmenting.
Windows defrag stated it was still fragmented after two runs. Typically I use Auslogics Disk Defrag and I don't have that issue and there is a noticeable difference when used as far as programs launching or moving files, even when using Windows built in defragger. So far, I am not overly enthusiastic with Glary Disk SpeedUp. Is it OK? Yes, for free but there are many better in my opinion.
