The Great Defrag Shootout XXII: UltraDefrag 1.0.5

UltraDefrag is the second open source defrag program, the first being JkDefrag, which I use regularly. You can find the project details of UltraDefrag on sourceforge.
It's still early days for this project, and version 1.0.1 didn't do much on my system at all. Version 1.0.5 is a lot better, and it took 6 hours to defrag my main drive. That's not particularly fast, but OK. The end result is shown below.
The program uses a process driver to access the hard drive, but there is very little documentation available to explain how it works or what it does. Hopefully that will come later.
There is no boot time defrag option, but there is a command line version for batch file usage or scheduled operations. The screen display is clunky and a bit sparse, and some of the colours used in the display are not explained. At this stage I would guess that the capabilities are roughly the same as the built-in Windows Disk Defrag utility, and not much more. I guess we'll have to give it more time, but it is worth watching.

Does this open source program work with DOS versions too?

Also, how is this windows disk defrag utility?

WDD is included with Windows, and is reviewed in article XI.

None of the programs reviewed here work with DOS or Windows 95/98/ME, since they all use the Windows NT/2000/XP/2003/Vista Defrag API calls.

I think MS DOS 5.x included a disk defrag utility, but it may have been 6.x. It works pretty well.

UltraDefrag 1.1.0 adds boot time defrag.

Donn, can you please check out the new 1.4.0 version that was released yesterday. It's much improved from the 1.0.5 version ... ;)
