When is a file actually deleted?
First, I'd like to say 'thanks' to Jethro and sOnic and the others who were giving me a lot of good answers in the live chat on this topic.
I thought this might be interesting as it is all over the news relating to security, terrorism, and hacking/cracking.
That kid a few days ago from Austria (I believe), who hacked into the Pentagon. If I were him, and I wanted to clean the evidence from my hard drive, what would I do? Because the 'delete' button (at least as far as I understand in Windows) doesn't really delete a file, it just deletes the pointer, correct? What about other systems, i.e. RedHat, BSD, etc.?
I think a tutorial may be in order here. Anyone want to volunteer?
So to summarize...
When is a file actually deleted from your hard drive?
