  PerfectDisk is a defragmentation software product for Windows developed by Raxco.
  
  The application keeps track of file usage to lessen defragmentation time and offers two modes of basic defragging: "quick" and "SmartPlacement".
  
  ## History
  
  During the 1980s, a software package titled "Disk-Optimizer" was marketed as part of the collective name "RAXCO Rabbit Software."
  
  PerfectDisk was released in 1990 for the VMS operating system. A version for Windows NT followed later in 1997. PerfectDisk contains scheduler supporting also client PCs in the network.
  
  ## Competition
  
  The standard Windows "Disk Defragmenter" is based on a subset of a competing, now-discontinued product named Diskeeper. For those seeking additional features, PerfectDisk and the full-feature Diskeeper are among their options; these are intended for high-end users, and feature optimizing the placement of "system files and free space."
