UltraDefrag 7.1.4 FREE/ UltraDefrag 9.0.1

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.

    Littlebits is NOT a review site, they are an advertiser site. The vendor that pays them the most money gets the best reviews. They don't even include any freeware products in their reviews what does that say about them? Many freeware products now days are much better than paid products. Auslogics Disk Defrag, Puran Free Defrag, IObit Smart Defrag, Defraggler and Glarysoft Disk Speedup are all top of the line products. UltraDefrag is bettter than most paid products, don't fall for fake scam review sites like Thanks.
