UltraDefrag is a powerful Open Source Defragmentation tool for the Windows Platform. It can defragment any system files including registry hives and paging file. Also one of the main goals of UltraDefrag is doing the job as fast and reliable as possible. It is very fast, because defragmentation is done by a kernel-mode driver. UltraDefrag comes with three interfaces: graphical, console and native.

• The representation of disk clusters on the cluster map was improved.
