How to Securely Delete Files Using SDelete
There are very simple command line in using SDelete to shred files securely:
-p passes Specifies number of overwrite passes (default is 1)
-s Recurse subdirectories
An example command line to securely delete the entire folder and its sub-directories is as follow:
sdelete –p 3 –s C:\Users\Donna\AppData\Local\Opera\Opera\profile\cache4
The above will delete entire contents of Opera browser’s cache, including the sub-folder in cache4. If you will not specify the number of passes, SDelete will use the default 1 pass only.
You can add SDelete in Send To or Context Menu in Windows if you will use a script. An example of this scripts is posted in SDelete forums.
Tip: It’s always recommended to delete files securely and wiping free space in your hard-disk, if you don’t really need them ever again. Secure deletion and wiping the free space will help protect your privacy because the deleted files can no longer be recovered by any local attackers or can help protect your privacy against spyware or adware.
