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. Defraggler was written in the same compact architecture as other Piriform products (CCleaner and Recuva). This results in a compact single EXE application, which can be copied to a thumbdrive and then used whenever you need it, without a complex installation process. The EXE itself is less than 1MB! Defraggler supports all OSs released since Windows 2000, this includes Windows 2000, 2003, XP and Vista. 64-bit support has also just been added! Additionally Defraggler supports both NTFS and FAT32 file systems.
