Oh, I know exactly how you feel. My brother likes to delete files on my computer just to be an asshole. I've learned to save my maps/scripts in two different places because of this.

lol wow! Is he older or younger? Have you tried putting a password on the computer? If you both share the computer, perhaps you should consider investing in an external hard drive to have handy. You can password protect those.
