The sound files folder

I need a sound effect (the slow motion enter and exit sound file) for a film. I looked in the folder called "sound" in the folder i installed mxo. But there's only like 2 audio files there. I remember seing the folder and actually playing the audio files a while back, so i know they're out there somewhere. Does anyone know where they are, or does anyone have them so they can send me those files?

Thanks!
