UltraDefrag speeds up the computer by defragmentation of files. When files consist of many little fragments scattered around the disk the computer needs more mechanical work to read them. Because of that the disk access becomes slower. UltraDefrag reduces the file fragmentation, thus it makes disk operations faster. Also the program can optimize a whole disk by placing small files close to each other, sorted by path (or other criteria). After the disk optimization less mechanical work is needed to read groups of small files. This reduces startup times of many applications including web and photo browsers.
In contrast with the most other disk defragmenters UltraDefrag can defragment locked files by running during the Windows boot. Actually all files including page and hibernation files can be defragmented there. Also UltraDefrag aims to be fast, simple, reliable and efficient.
UltraDefrag runs on Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and Windows 7, including all 64 bit versions of Windows. UltraDefrag v6 supports Windows NT 4.0 and Windows 2000 as well. UltraDefrag cannot be used on DOS, Windows 9x, Windows NT 3.51, ReactOS and Mac OS since these operating systems provide no defragmentation API. However, Linux port of UltraDefrag exists. It is based on NTFS-3G capabilities.
