I've been a fan of O&amp;O's defrag for a few years because it reorganizes files according to a set of rules as it defrags. It will put everything in order on the disk by name or by last accessed date for example.

With version 10 we can finally have defrag jobs run whenever Windows goes into screensaver mode! As if that weren't cool enough by itself, they also include a screensaver as part of the install package. Here's a crappy digital camera shot of my screen with the O&amp;O screensaver in action.

On the left side of the screen file names with their full path scroll up as they are defragged &amp; taken care of. The image map of your defragmentation in process spins and rotates in a 3D space on the right. It almost looks like something out of CSI Miami or some Sci-Fi show. You certainly don't need to be running O&amp;O's screensaver in order to have their software defrag while your PC is running a screensaver... it works just fine using my favorite Power Dimmer screensaver -&gt; http://www.whitsoftdev.com/powerdimmer/
It also uses the new Vista style interface/window design.  I forget the actual name for this style ATM but Office 2007 uses it too.

It also has report pages you can save... but the formatting of the html is all weird with spaces between every character. The .htm file works in IE and Firefox fine as a local file, but when served from Apache Firefox doesn't like it.
