open source defrag utility

UltraDefrag

UltraDefrag doesn’t have a flashy interface, but it is effective as far as free defraggers go. It was created by the UltraDefrag development team as an open source alternative to other commercial defragging utilities. The default interface is graphical, but there is a command line option. This utility is available in 32 and 64 bit versions, so choose the right one for your system. You can run it as Windows boots up. Or you can just set up a schedule so it runs on a specific time. UltraDefrag is very simple to use. Launch the program and choose the drive you want to defrag, analyze or optimize. The defrag option is self explanatory. The Analyze option displays a graphic sector table. It shows where on the hard disk your files are.
