Next: Simulation And Experimentation
Up: Third Party Disk Defragmentation
Raxco Software produces a disk defragmentation program
called PerfectDisk NT. PerfectDisk does not patch or
bypass the file system. It also does not require
multiple passes. [Sof]
PerfectDisk categorizes files into three categories.
- Warehouse files are files that have not
been accessed for a long time. PerfectDisk puts
warehouse files at the outer edges of a disk.
- Ordinary files are files that have been
accessed recently. PerfectDisk puts ordinary files next
to warehouse files (but closer to the center of a disk).
- Volatile files are recently created files
that are most likely to be accessed, edited, or deleted.
Volatile files are collected together next to the free
By organizing files in this fashion, a full disk
defragmentation requires twenty percent less time than
would otherwise be required. In addition, there is a
thirty percent improvement in performance just by
consolidating volatile files and free
space alone. [Sof]
