    I've never used the default windows defrag thingy before, so I can't compare, but this one seems to do just great.

    Excellent tool. Sped up the boot time and desktop loading a surprising amount on my my fiance's 6 year old laptop using the new "zones" feature in v12. There's a 30 day trial, give it a go and see if it works for you.

    Great! The best defragmentation tool I've ever seen. A lot of functions, options, interface is ok. It isn't freeware at all :/ shame

    Autodefragmentation - that's all I need. It checks, it decides when my system needs defragmentation, it defragmentates

    cant say I'm happy about the interface, but the program itself works wonders... better than any other degrag util I've used.

    Could do with a few more options too.

    Best defrag app on ms windows.It has few ways of defragmentation,interesting features and ugly ms office 2008 like interface.

    Overall:

    Some great defragging options and the ability to consolidate your files together reduces seek times and makes it very simple to partition a drive.

    Overall:

    Probably the best defrag tool around. It is a bit slow in defragmentation process, but it offers a wide range of settings and improvements (defrag by access date, space, file name etc...). Offline Defrag (at system boot) can defrag even system files wich usually are not touched by other tools. It's absolutely worthy of the price...

    Overall:

    Fantastic defrag program, does a way better job than Windows defrag and really does speed up your system noticeably. Latest version works and looks great (Office 2007 tool ribbon) and works well on Windows Vista.
