Defragment system files

Suggestion:

Add an option called "Defragment System Files". With this option DF could defragment a whole bunch of system files:

- files/folders that start with "$.......". E.g. "C:\$extend\.......... ". (This is based on the assumption that these files/folder can be moved & defragmented). File(name)s that start with "$........." seem to be moved by DF.

- System Restore Points (can be done in Windows XP).

Perhaps there're more (system) file/folders that can be defragmented ?

But then these system files shouldn't show up in the "regular" file list. And don't mention what system files are defragmented.
