I don't know. That is sth I have to find out. The problem is that if you
simply delete a file in say Windows or Linux you don't rease it you only
delete the link. So unless the OS has overwritten the place the file
occupied with new files one can recover it.

I guess one could change every byte in the file with 0 and then write
the file again before deleting it.

But thanks for the pointers I'll check it out.
