UltraDefrag is an open source disk defragmenter for Windows operating systems. It is very fast, because the defragmenting is done by kernel-mode driver. UltraDefrag makes use of the same defragmenting API used by many other windows defrag utilities, both open and closed source.

UltraDefrag has many unique features . Firstly it has a kernel mode driver that does most of the work. Secondly is the ability to run the application at boot up time in a manner similar to chkdsk. This allows for faster defragmentation time and the ability to defragment all files including system files. It can also defrag single file or multiple directory, generate a list of all fragmented files.

The program is available for both 32-bit and 64-bit version of Windows running on both AMD and Intel based processor. There are three interface available: Graphical, Console and Native.

The UltraDefrag Micro Edition is a special package for advanced users who prefers extreme stability and power. This edition is a little bit faster, much stable (its driver contains just most important parts). It has console interface to speed up defragmentation process. Boot-time defragmentation feature is available too. The Micro Edition saves reports in plain text format.
