Pretty goodby WickedCronic Dec 12, 2013 (Read all my 2 reviews)

I use Defraggler v2.16, however after running this product I had to go into settings(for Defragglerv2.16) and make a few tweaks to best the performance. Final score was 1140 fragmented files at for Defraggler v2.16 & 1129 fragmented files for IObit Smart Defrag, so a really close call... Review details

Works goodby gimpguy Sep 11, 2012 (Read all my 1159 reviews)

As most defraggers, for free, it's very good, deserving of a 5 in this regard. It works well, fairly quick, does a decently thorough job. The interface is good, no issues. Review details

Great program!by dem232 Jul 16, 2012 (Read all my 3 reviews)

There are many free de-fragment tools out there, but for me this takes the cake. It's features are at the same standard as all the other great freeware defrag tools on Snapfiles, however the auto-defragmentation feature is a blessing which keeps your HDD maintained at all times. Highly Recommended! Review details
