UltraDefrag is a disk defragmentation utility for Microsoft Windows. Prior to version 8.0.0 it was released under the GNU General Public License. The only other Windows-based defragmentation utility licensed under the GNU GPL was JkDefrag, discontinued in 2008.[1]
In 2018, UltraDefrag sources have been relicensed to Green Gate Systems. Their enhanced 8.0.0 version, released under a proprietary license, features automatic defragmentation and is said to have much faster disk processing algorithms.[2]
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.[3]
Jean-Pierre André, one of the developers of NTFS-3G, has created a fork of UltraDefrag 5 that runs on Linux. It only has a command-line interface.[4]
