UltimateDefrag

Apparently the CL version is completely free, but the GUI version you are "required" to register for a fee. However, from using the GUI trial, I'm not sure what features are disabled, or if you actually have to register at all even though the site and prog say you have to. Other than those quirks, it seems like a great program. Do you know what happens when you select "compact" as opposed to the normal defrag? (it takes a LONG time to run)

Had a quick look through their forums and apparently the unregistered version does a slightly less thorough defrag (another reason to use the CL version ;) ). The 'compact' function is explained on the following page under the "Squish out small gaps between files" heading :D:

How then is the CL version different from Defrag.

I haven't tried Dirms but it sounds nice. The main differences with Defrag v2.27 seem to be that Dirms does not order the directories to the beginning of the disk, does not maintain a scratch area, does not reclaim MFT space, and does not come with sources. Also, according to their website it's not free software (the commandline version), you have to pay $10 if you want to use it legally past the free trial and to unlock all the functionality.

I would think the advantage to using a defragmentation program via command line is that system resources are sparred.

Yes, the commandline version of Defrag uses less system resources, but the main reason for using the commandline version is that you can automate it. GUI programs can usually only be controlled through the GUI (clicking with the mouse), which is useless if you want to start the program from another program, such as a script, or a webserver administrator panel.

Would htat then not be the case using dirms' service driven product(s)?

According to messages on their forum Buzzsaw uses a lot of memory.

Also, according to their website it's not free software (the commandline version), you have to pay $10 if you want to use it legally past the free trial and to unlock all the functionality.

Sorry but thats just wrong, I've been using it for over two months now, downloaded from their site, no registration, full functionality and works a treat.

The fact that you can use Dirms without paying doesn't mean Dirms is free software. If you want to use Dirms legally (including the commanline version) then you have to pay. The Dirms website is quite clear about that. Secondly, according to a posting by the Dirms programmer on the Dirms forum, if you don't register then "it doesn't defragment all the directories". It's a small thing and perhaps you haven't noticed. So I maintain what I said, Dirms is not free software, you have to pay to use it legally and to unlock all the functionality.
