HELP!! Soundfont problems...

[T.A.Z]

Ok i just got a new soundcard, a Creative Soundblaster X-Fi Platinum, a monster of a soundcard, however i need to learn how to use it a little more I think.

But my problem is that when I have downloaded .sf2 files they don't come up as .sf2 files its like the computer can't register the file and doesnt know what to do with it. So when i set-up the directories in FL, a message comes up at the top of the screen saying "directories are empty". I was wondering if anyone else has had this problem or at least know how to fix it I want to start making BTs ASAP!!
