When it comes to personal privacy, I would say I am a bit more of a stickler than most. For this reason I think that everyone should know how to permanently delete files. If you have to take your computer in, let someone onto it, or just lose control of it for some reason, all of the files on your hard drive are open game. I don’t like the idea of someone going through anything of mine so I learned how to delete things and make sure they stay deleted. I also think this is useful for many other reasons, but privacy is the biggest one in my mind.
