JkDefrag is a free open source disk defragmenting utility computer program for Windows. It was developed by Jeroen Kessels beginning in 2004[1] and is released under the GNU General Public License. The "Jk" part of the utility name is taken from the developer's name, Jeroen Kessels. In 2008, from version 4, much changed from previous versions; JkDefrag was renamed MyDefrag by its developer, and JkDefrag was discontinued, although still available. MyDefrag is closed source freeware.

Operation

JkDefrag has many options. If run without options it groups files into 3 zones with the intention of optimizing speed:

  1. Directories and system files
  2. Regular files
  3. Large files referred to as "space hogs" in the documentation

Files outside their zone are moved to their zone. Directories are perhaps the most accessed data on disk, so zone 1 is placed at the beginning of the drive. After the directories comes a free space area, then zone 2 with regular files, another free area, and then zone 3 with "space hogs", which are large files, archives, recycle bin contents, service pack files, and other infrequently accessed data.[2]

JkDefrag characteristics:

JkDefrag runs on the Windows 2000/XP/2003/Vista Operating Systems, and defragments both FAT and NTFS filesystems. It uses the standard Windows defragmentation API. User support was provided through web-based forums.

Related software

There are several graphical user interface utilities designed to work with JkDefrag:

The only other Windows-based defrag program with a GNU GPL is UltraDefrag.
