JkDefrag is a free open-source disk defragmenting utility computer program for Windows. It was developed by Jeroen Kessels (initials "JK", hence the name) beginning in 2004[1] and was released under the GNU General Public License. Since version 4 of 2008, much changed from previous versions, JkDefrag was renamed MyDefrag by its developer; earlier JkDefrag versions continued to be available. MyDefrag, which was closed source freeware, was discontinued, with the last version being v4.3.1, file date 21 May 2010; for several years the MyDefrag website has been a redirect to the still-existing JkDefrag site, but links to downloadable JKdefrag files are dead. JkDefrag source code is still available from third-party websites [2]
