Split a large fla into multiple

Hi,

I have a quite big fla which has multiple movieClips in it.

Stupidly, I didn’t make them all in separate FLAs initially. But now I want them to be made into separate FLAs so that I can make the parent FLA lighter and load those individual swf as and when I require.

Now, to do this, only way I am able to think of is create a copy of the main fla and then delete everything other than the particular movieclip i want. And so on and so forth.

But I am sure this is the stupid way of doing it.

Could someone please point out how to go about it?

Thanks,
Mukesh
