Is it OK?
If you wont agree, I’ll delete it.
Thanks.

what I have nout found yet is a program that erases *already deleted* files. If, for instance, confidential documents are scanned, the scan software usually generates temporary files on the system volume (containing the confidential information) and deletes them automatically after the final picture file of the scanned document is finished (typically on an encrypted and/or external volume). These deleted temporary files could be undeleted and read, as they are not overwritten. To my knowledge, the only secure method to erase these remains of confidential data is to “erase free disk space”, which some programs can do, but this is very time consuming. What one would need for this case is a program which first undeletes all files which have been deleted in, say, the last few hours, and then erases them. Does anybody know if such a program exists?

Just a note to mac users out there -
This comes built into mac OS X, at least in tiger (10.4), and possibly earlier versions.
Just put the files into the trash, and choose ‘Secure Empty Trash’ from the ‘Finder’ menu.
If you are deleting an entire drive, there is an even more secure version of this available from the Disk Utility.
