14 DAY TRIAL // It took two beta builds and three release candidates for UltraDefrag 6.0 to be promoted to a stable revision.
Although the difference from RC 3 and this build consists only in updating the translation for Chinese (Traditional), UltraDefrag 6.0 adds several improvements that affect disk processing algorithms, file optimization as well as overall functionality.
Starting this revision, users can check on the progress of a defrag task in the taskbar of Windows 7 and above; furthermore, the application window can be minimized to system tray area.
The developer added new filters for fragment and file size and the entire defragmentation procedure has been optimized for speed and efficiency; the Explorer context menu handler is also configurable in this version.
UltraDefrag is available for download on this page; it is also available as a portable download.
