Publisher's Review:

UltraDefrag 6.0 is an open source disk defragmenter for Windows NT 4.0 and later 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. However, UltraDefrag has many features that makes it unique. 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 and can generate a list of all fragmented files. The program is available for both 32bit and 64bit 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 feature is available too. The Micro Edition saves reports in plain text format..

(UltraDefrag version 7.0.0 beta 1)
- This release gets rid of our home-brew GUI framework, which is replaced by wxWidgets
- This allows us to focus on the defragmentation engine and implement some long requested features
- The only drawback is that we have to retire support for Windows 2000® and below
- The translation is now moved from our home-brew one to GNU gettext, which is shipping with wxWidgets
- The translations are hosted online at Transifex and shipping with UltraDefrag for offline translation using PoEdit
- All translators are encouraged to read the Translation section of the handbook for further information
- This release doesn't offer any new features, it is meant for testing the migration of the entire GUI code
- Please give it a whirl and report back any problems you encounter
- The executables are not yet optimized for size, which will be taken care of before the final release

(UltraDefrag version 6.0.2)

- The Explorer® context menu handler now uses a sub-menu on Windows 7® and above
- The handbook now includes a FAQ entry about how to set up optimization to work similar as in v5.x.x
