When I look at all recoverable files, and then wipe them out with the Gutmann method, I always find "Thunderbird emails.zip", which is always recoverable. But it won't let me delete it.
I understand that the ability to recover old emails is a feature of Recuva, which will definitely help many people, but I'd like the option to securely delete that file as well. Is there a way to do it? Is there another program that will let me do it?
