DiskState includes a Deletion Engine to clean
up specified folders ignoring user-definable files, files older
than a given number of days and so forth. Works with all files in the directory tree and
can also delete empty folders upon selection. The engine can also be told what to delete,
in addition to what to ignore. Furthermore, the engine might be configured as an historical file
archiving engine.
The engine is only available under Windows 7/Vista/XP.
