File recovery and Destruction
84 TuneUp Utilities 2006
Quick delete: The files will be overwritten with a single character. The files no
longer contain the original text, but endless columns of a single letter.
Secure delete: A method that was developed by the US Department of Defense
(Regulation DoD 5220.22M) is used. The files are overwritten with special data
patterns multiple times before deletion, thereby destroying the original contents
so effectively that even expensive examinations of the magnetic structure of the
disk in a special laboratory cannot recover the data.
Under Repeat the delete operation, specify how many times you wish to have
the selected deletion method repeated. The security of the deletion can be
enhanced further by increasing the number of repetitions, but the time required
will also increase.
Click Next to start deletion. Please wait until the program is completed. If you
do not wish to delete any other files or folders, you can close the wizard by
clicking Finish.
If you wish to delete additional files or folders, click Back.
Shredding a File after deletion
If you have already deleted a file by “normal” means, the only way to reliably
destroy it is by using a special tool that overwrites all free space on your drives.
Tip: When you defragment a drive, any deleted files are normally overwritten in
the process and cannot be recovered afterwards.
