Purge 2.0
~~~~~~~~~
This program works much like the AmigaDos command Delete, except it
completely erases the file in such a way that it's impossible to
recover. Files erased with Delete can often be recovered with
programs such as DiskSalv, or Quarterback Tools. Not so with
Purge. If you want to free up space on your disk, use Delete, but
if you want the file to be gone, permanently, use Purge.
usage: Purge <filename>
All AmigaDos wildcards are fully supported. Purge is pure, and can be made
resident. Purge works by writing random data over the file before deleting
it. By doing this, even if the file is later recovered, it will consist of
nothing but garbage. The disadvantage over the delete command is that
Purging a file can take quite a bit longer than deleting one.
