Macromedia Flash Files

Copy the preloader clip form root of the file and paste it in first frame of your flash file, move all your other content to second frame. When file loads the preloader will stop the timeline and will play the loading animations, when loading is done then it will tell its parent level to go to and play second frame (your file content).
