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, but its GPL version was discontinued in 2008.[1] In 2018, UltraDefrag sources have been relicensed to Green Gate Systems, LLC. The enhanced 8.0.0 version features automatic defragmentation and is said to have much faster disk processing algorithms.[citation needed]

UltraDefrag uses the defragmentation part of Windows API and works on Windows NT 4.0 and later. It supports FAT12, FAT16, FAT32, exFAT, and NTFS file systems.[2]
