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. MyDefrag website is defunct as of 2016. The JKdefrag website is still active, but all download files have been removed. OperationJkDefrag has many options. If run without options it groups files into 3 zones with the intention of optimizing speed:
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 softwareThere are several graphical user interface utilities designed to work with JkDefrag:
The only other Windows-based defrag program with a GNU GPL is UltraDefrag before version 8. See also{{Portal|Free and open-source software}}
