Alternatively called disk compression, a disk optimizer is software designed to organize or compress data to maximize free disk space.

An example of a disk compression software program is a Microsoft Windows utility known as double space.

With today’s large hard drives, disk compression utilities are no longer used and no longer recommended. A disk compression utility should be used on hard drives of 1 gig and smaller.

The Microsoft Windows defrag utility is considered a disk optimizer, and is still commonly used and recommended even on large hard drives.
