Anything in this that can give you any ideas?

Interesting! I didn't know about that defragger. I have looked at the link, it was registered on 2007-06-25 so it is very young and new. There is no mention of optimization on the homepage, but there is a mysterious "compact" button in the screenshot. I see the author has build it as kernel-mode driver, that's a little bit dangerous and makes the sources a lot more complex. It does mean the program can potentially be run before Windows is fully booted, and can potentially run in the background for continuous defragging, though. A quick look at the sources tells me that the program uses the Microsoft defragmentation API, just like JkDefrag, so it will have the same limitations.

Though it has very nice and graphic enough interface

I like there Gui better than this one but i don't the how the program defrags so far this on dos a much better job

Unfortunately, it appears to be pretty bugged!

When I tested it under Windows 2000, Windows 2000 had a fit, Windows 2000
started giving

Code:

Windows-system error

  Unknown hard error

      OK

pop-ups and logged a warning in the event log about the data being lost in the cache!

Unlike JKDefrag, it apparently uses a buggy kernel mode driver.

Again a new one (a little brother to CCleaner and Recuva): Defraggler. A very, very basic one.

Downloadable here.

But it looks like UltraDefrag. Stolen code from UltraDefrag?
prove me wrong if it isn't.  :wink:

I downloaded it. I clicked on "analyse". Result : this drive contains no fragmented files.

Thanks JKDefrag.  :lol:

First impression: Analyse takes much too long... Also, the analyse feature somehow prevented my Acronis backup from running (Acronis could not read some files), JKDefrag never gave me this problem.

It doesn't seem to be. Defraggler is much closer to Defrag-A-File from PC Magazine in terms of user interface and philosophy. Also, I don't think the Piriform programmers would "borrow" code in this way, although there is nothing stopping a programmer from reading the code from either UltraDefrag or JKD in order to see how things are done.

I have tested Defraggler and an earlier version of UltraDefrag, and I think that JkDefrag is superior in approach, and far more mature in implementation.
