UltraDefrag is an open-source disk defragmenting utility for Microsoft Windows. It is released under the GNU General Public License. The only other Windows-based defragmentation utility with a GNU GPL was JkDefrag (GPL version discontinued since 2008).

History[edit]

UltraDefrag was originally written by Dmitri Arkhangelski in 2007, who was later joined by Justin Dearing who wrote an original user manual and UltraDefrag Scheduler application. Later Sayem Chaklader joined the team to completely redesign the project's website. Also he improved graphics belonging to the project. In the year 2009 Stefan Pendl joined the team. Most new features and improvements since that time were invented by him.[citation needed]
