need help, finding game files

this is going to sound really stupid, but i've installed the game from disc, done all the steam activation stuff, the game loads fine. my question is this: where are the game files installed? i know where the files are where you add graphics n whatnot. but i'm talking about the GBs of game files? i never had 2012 but had 2011 and it installed the bulk files in Program Files, under a directory called sports interactive. can't for the life of me find em on 2013!

any help would be appreciated

nevermind, i found 'em. didn't realize they'd be tucked away in the Steam directory.
