I have a movie with ScrollPane component

When exporting the size report is like this...

Frame # Frame Bytes Total Bytes Scene
------- ----------- ----------- ----------------
1 37852 37852 Scene 1 (AS 2.0 Classes Export
Frame)

How can I know what Class files is the movie using?
Can I put this .as files externally to swf ?

I will have a lot of different movies with ScrollPane inside them and I
would like not to increase size of all this files with this 35 Kb of code.
I would make this code externally and common to all swf.
Is it possible?

Thanks.
