I installed and executed the program in VMware and received a BSOD...
Think I should submit the .dmp file to the developers for analysis? :P
Resetting the VM and executing the program again complains that it cannot find the driver. Needs some work.

I'm using JkDefrag myself and I'm pretty happy with it, but I'm always willing to try out a new program. I was a bit suspicious about this one.
I think this one needs some recoding, but it could be my computer. On my computer this program works incredibly slow. I don't know about the defragmentation speed, but it sure takes a long while to analyze a disk.
And well, then the program crashed. Actually, I got a BSOD. "BAD HEADER" or something like that. I didn't get that with other programs before...

Then again, could be my errornated computer.

...and as such, doesn't work on any x64 version...unless both versions exist in the same package...which is probably not the case, since x64 isn't mentioned anywhere.

Confirmed on the download page--32-bit only

And yeah, I agree with phiberoptik above--if it doesn't support NT 4, don't call it a defrag tool for NT.

the program works with Windows NT 5.0, NT 5.1, NT 5.2, and NT 6.0.

obviously calling the program a defrag tool for "NT" is an Ok thing to do, as THAT IS WHAT IT IS. it doesnt work on the Win9x or DOS kernel, only the NT kernel.

just because it doesnt work on NT 3.x or NT 4 doesnt mean its not an NT defrag tool.

Microsoft has dropped the "NT" nomenclature years ago, and any technical documentation of theirs referring to anything called "NT" refers to 4.0 or older. Using "NT" to describe the OSes your products supports, while at the same time *not* supporting NT 4.0, is misleading at best.

hmmmmmmmmm

Come back when you have a true circular disk display and all the other features a defragmenter should have.

Does the ability to view your fragmented files in a nice circular picture make defragging said files more efficient?

That's beside the point. Your disk is circular so the drive display should be circular. Plain and simple.
There are more than 20 defragmenters in existence, some of which do a damn good job. This is just another one that I have to test and add to my comparison I'm doing.
