Switching out sounds?

I used very big sound files in my game, but I've now switched them out. But the sounds are still in the .mfa file (You know, when you click "Play Sample" the sound is in the list). And therefore, the game's size
becomes very big. The sounds doesn't go away, and I'm not using them in the game. So I was thinking of switching out the sounds with samples which lasts 0 seconds, that will probably fix it. So, is that possible?

PLEASE HELP!

Switching out samples from the list (The application), or removing them.

Close and re-open MMF and they will be gone.

What Marv said. If that doesn't work then you need to double check your events because there would have to be an event that still references the sound.
