PerfectDisk is a very good application for defragmenting system partitions based on a Windows-supported file system. The program offers features such as StealthPatrol mode for automatic defragmentation only when the computer is idle or PerfectDisk's Single File Defrag option to allow the user to select any file to defragment. PerfectDisk is also equipped with the function of automatically releasing space from such locations as Basket or temporary Internet files.

This function has also been extended by a search module for duplicate graphic, text, music and video files. In addition, PerfectDisk can be operated from the command line for both local and remote operations. The command line is very extensive and allows administrators full control over the process of optimizing files on hard drives.
