CNET Editors' review
For whatever reason--maybe just nostalgia--people are hooked on the old Windows defragmenter cluster map, with the little colored squares rearranging themselves into their unfragmented positions. Ultra Defragmenter brings this interface back, and although it definitely kicks it old school as far as the visuals are concerned, we're not sure it works much better than the built-in Windows defragmenter.
The program's interface is plain, displaying the list of volumes, the cluster map, a progress bar, and a handful of buttons. We had the program analyze our hard drive and then started defragmenting. The program seemed to take about as long as the built-in Windows defragmenter, if not a little longer; it wasn't terribly slow, but it didn't impress us with its speed, either. Once it was finished we opened the Windows defragmenter and analyzed our hard drive with that. Even though we'd just defragged with Ultra Defragmenter, the built-in utility showed that our drive was still 20 percent fragmented. We ran Ultra Defragmenter again, analyzed the drive, and found that the fragmentation was down to 19 percent. So although Ultra Defragmenter looks cool, it doesn't seem too terribly effective. The program does get points for having a thorough online Help file that explains all the ins and outs of both Ultra Defragmenter and the defrag process in general. Overall, Ultra Defragmenter isn't a terrible choice--especially if you really miss the cluster map--but it's probably not the best option if you want a really thorough defragmentation.
Ultra Defragmenter installs politely but leaves a folder behind upon removal. We recommend this program to everyone, provided that you don't mind form trumping function.
Publisher's Description
From UltraDefrag:
UltraDefrag is a powerful open source defragmentation tool. Its engine is very fast, because it is created as kernel-mode driver. They are three interfaces to them: graphical, console and native. First is very useful, because it use cluster map visualization. Console is good for task scheduler, and native tool - for advanced users and programmers.

"Optimizer function extremely slow"
Version: Ultra Defragmenter 4.4
Pros
Defrag is fast
Cons
I am running the optimizer on my 500 GB hard drive on a Vista 64 system. It has been running for over five days and is only 64% done.
Summary
Okay for defrag but stay away from the optimizer
-
"Too slow to use, just like the windows defragmenter"
Version: Ultra Defragmenter 4.4
Pros
Looks good but then looks are not everything.
Cons
I found the Ultra Defragmenter too slow, so I uninstalled it
Summary
I might be ok to use if you have plenty of time, but I preferred the old one, so I have gone back to it.

"Excellent product for XP users"
Version: Ultra Defragmenter 4.4
Pros
Much better for defragmenting than XP's built-in defrag program
Cons
Not entirely safe - can cause errors if interrupted in the middle of a process
Summary
This program is a big improvement for XP users, since XP's defrag program is poor quality. Does a much deeper and more thorough defrag than XP. The "Optimize" function provides a noticeable improvement in performance. However, the "Optimize" function is VERY slow - on some of my machines it took 36 HOURS to run! If it's interrupted at any time during these 36 hours it can cause disk errors that are hard to repair. This program is not needed for Windows 7, which has a good built-in defragger. Overall, it's a good program, but be careful with it.
