Import a Scene or Fla file into a Flash Document

Ok, i have created a preloader in the first scene of a flash document. I need to get content from another flash document into scene 2. It appears that i have 2 options:

Either 1. import my other fla document into the next scene 2
OR
2. I import the relevant scene from my other fla document into scene 2.

Does anyone know how to do this??

Thanks
