Files can remain on your Mac even after they have been deleted or moved to the trash. Indeed using techniques like magnetic force microscopy data can be retrieved even after your drive has been formatted.
The only sure way to delete files and clean up your free disk space ( where files previously moved to the trash may still lie ) is to overwrite them many times using well-known bit patterns so that they can never be recovered.
Using advanced techniques SecretShredder will clean your drive so that data never comes back.
Just drag files onto the dock icon. Or type apple T to shred the trash, it's that simple.
