Publisher
The program is published by Auslogics Software Pty Ltd, an Australian-based company that specializes in maintenance software for computers that run the Microsoft Windows operating system. Started in 2008, the company gained recognition for its two most highly rated products – Auslogics BoostSpeed and Auslogics Disk Defrag. In 2009 the company partnered with Sony Vaio to develop part of the Sony Vaio Care software installed on the Vaio laptops and desktop PC's.

History
Released in early 2007 as the first public non-beta version 1.1.2.208, the programhas gone through many updates, bug fixes and improvements over the years. It has always been distributed as freeware, gaining popularity as a substitute for the Windows standard defragmenter. With over 10 million estimated users worldwide, the publisher has introduced multi-language support with more languages being added from version to version. On February 1, 2012 the publisher released the professional version of Disk Defrag, with the free version remaining and differing from the new professional one in functionality. As of this date, the two versions of the application are given the names of Auslogics Disk Defrag Professional and Auslogics Disk Defrag Free to differentiate them.

The fact that the application is available for free for home use
The new professional edition of the application, Auslogics Disk Defrag Pro, since being released in early February 2012, has also been tested and reviewed by the main industry magazines and online authorities. It received 4.5 stars from online software analysis and review publication Betanews. They note its configurability as one of its main advantages, while listing lack of local help as a disadvantage due to the program's manual being available only as an online download. Disk Defrag Professional was also reviewed by the major industry magazine PC Advisor, which called it a "very powerful defrag tool" and noted the program's many customization options as an advantage.
