Publisher's Description
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.

Well this project went bad fast and it basically crippleware now, now offering a 'paid' version for features that are available for free in plenty of other closed source projects..
I recommend puran defrag, 100% free and has all the features you need.

working faster then befor.. did a perfect job on analisis. did a full opt for a 400g drive 60% full and was in poor order.. did the job fine and quicker then befor.. using amd64 8 gig memory .. have tried many optimizers.. but this tends to work better overall and if run regually keeps things neat less any stutter for many files. WIsh it had a put system files for windows in fastest section of drive.. ie for spinning rust .

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.
3 1/2 stars

A very nice update to a good little utility.

All Day? This is one of the fastest defrag utilities I have ever used and this version is faster than the last.

Keepsgetting better and better. I like to use this from safe mode with command prompt for a thorough defrag.

Tried in the past and didn't think much of it. Has improved much since. However, did not detect my USB keyboard on boot-time scan(was supposedly fixed in version 5.xx). Default context menu insertions are overly ridiculous, but I got rid of them easily via regedit.
3 1/2 stars..... 4 stars when the USB keyboard problem is finally fixed, if it's even fixable.
UPDATE: My bad, the keyboard IS seen on boot-scan startup. 4 star program.

A good update to a very nice little utility. Finding the 64 bit version is a bit of a chore. But over all a definite 5 star pick.
