Question about levels

I have searched for this but can’t find an answer and am unsure what search terms to use.

What I want to know is - if you build a swf that has lots of levels (say from using createEmptyMovieClip), and then you load that swf into a movie clip(containerMC) on another swf - does the first swf still contain all those levels? Or is it flattened?

And if it is flattened - how do you reference the clips that were on those levels? Can you just use _root.containerMC.instancename? where instancename is the name given to the clips that were created inside the createEmptyMovieClip

I’m not sure this makes any sense but if someone can follow this unravelling of my brain please let me know what you all think!

Thanks - :hr:
