MyDefrag 4.3.1J.C. Kessels – Freeware –
out of 82 votes
MyDefrag is extremely solid because it is based on the standard defragmentation API by Microsoft, a system library that is included in Windows 2000, 2003, XP, Vista, and 2008. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters. Basically all MyDefrag does is send "move this file to that location" commands to the API. The API is part of the operating system and can safely move almost any file on the disk, without risk and while the computer is in full use.
