Make JSON files to have TextMate2 icon I have all the JSON files on my system set to open with TextMate 2.
When I get Info on one of these .js files, I see the TextMate 2 icon on the corner. But, how do I make for the TextMate icon to appear while in Finder's icon mode too?

I'm using Mountain Lion, if that makes any difference.
You must go to settings -> icons settings -> set files icons.
