UltraDefrag is powerful Open Source defragmentation tool for Windows. It is very fast, because the defragmenting is done by kernel-mode driver. They are three interfaces to them: graphical, console and native. The GUI is very useful, because it represents your filesystem visually as a color coded cluster map. The console is another option for those that prefer the command line. It is also allows you to run UltraDefrag from the task scheduler and scripts. Finally, the native executable will run at boot time in a manner similar to chkdsk.
Hard Disk Tool
Disk fragmentation leads to system slowdowns, PC crashes, slow startup and shutdown and sometimes to system failures.

Get the maximum performance out of your expensive hardware investments, improve your computer´s performance and stability.
Most defragmentation tools only let you defrag the whole drive. Defraggler gives you the power to select individual files and folders to defrag. So you can get the job done in seconds, rather than waiting for the whole drive to complete. Of course if you want to defrag the whole drive Defraggler will let you do that too.
