The one thing the program lacks is threading and as a result you cannot analyze and defrag multiple drives at the same time, which you should be able to do to save time when doing it manually. It defragmented the entire 1 TB hard disk in just under fifteen minutes which is fairly fast.

It analyzed my 1 TB hard disk and found 27gb of fragmented files in less than 2 minutes. The program is very small and light weight and installs in seconds, and one of the things I liked about Defraggler is how fast it was able to analyze my hard disks.

I am always looking to test out and try freeware and software that will help improve and optimize my Windows 7 Ultimate machine and recently I stumbled across Defraggler from Piriform which is a really nice and fast free disk defragmentation tool.
