UltraDefrag 7.0.1 – Final

UltraDefragUltraDefrag 7 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. 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 UltraDefrag 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.
