UltraDefrag is powerful Open Source defragmentation tool for Windows NT. It is very fast, because the defragmenting is done by kernel-mode driver. They are three interfaces to them: graphical, console and native. The GUI is very useful, because it represents your filesystem visually as a color coded cluster map. The console is another option for those that prefer the command line. It allows you to run UltraDefrag from the task scheduler and scripts.

    Extremely unimpressive program. Ran a full defrag with it on one of my drives which was mostly defragmented to see what it would do. It started pulling data and writing it to the END of the disk, leaving 50% alone and moving 50%.. continued on like that, doing nothing else, for about ten minutes. When it was halfway completed I quit out. I don't know what it was going to do after it finished, but a regular defragmenter analyses data and moves it if necessary. MyDefrag placed the data properly, and doesn't do a massive amount of work on already-close-to-defragmented drives. Avoid this program, the defrag algorithm looks pretty useless.

    faster is NOT better..... I can do an 8 hour defrag with o&o defrag and the results are amazing

    "- The Explorer context menu is now reduced to a single entry with sub-menu on Windows 7 and above"

    How about an option to NOT have context menus during install. Guess that would be asking for too much. Good thing there's no real reason for me to update to this version.
