Can this be done? I'm doing a powerpoint presentation about mp3's and in it I play a song. But when I check the file size, the thing is just like 70k. Shouldn't it be the size of the mp3 (3.5 megs) + filesize of the PP presentation? That leads me to think that it is just linking that mp3 to my presentation, I know it will work on my PC, but what do I have to do to make it play the mp3 on someone else computer? Help please.
