As opposed to an admin who thinks he's above user preference?
Who are you to dictate file extensions? What if he didn't want to use them at all? What if he had never heard of those particular extensions. What if another program used the same extensions?
You remind me of the admin who blindly deleted someones file called "penis" that contained biological research data.
He didn't get away with it. I'm surprised that you did.
