UltraDefrag is powerful disk defragmentation tool for Windows NT that's extremely fast and, uniquely, works during boot time.
UltraDefrag doesn't really look much different to any other defrag tool but the developer has obviously tried to keep it to a bare minimum to make it lightweight and fast. UltraDefrag is open source, so it's completely free. It can be run in two modes - console mode and advanced mode.
In advanced mode, you can instruct UltraDefrag to ignore certain files that you don't want defragging or reorganizing. The litmus test though is whether it really makes a difference to the speed of your system afterwards and it doesn't make a huge boost in operating speed but it definitely feels slicker for a while.
Fast, free and easy to use, UltraDefrag is definitely worth a try if you're not happy with Windows defrag tool.
