Can someone answer a ? for me

:thumb:

My question is where do I put the perloader?

example:
Main movie + 3 swf files. ok I want a preloader to come out before the swf MC loads. Do I put the preloader in the main movie or do I insert the preloader in each one of the swf files.

If the preloader is inserted in the main movie how can I make it show before the MC play.
