I’m doing some “clean up” on a Flash file for size optimization, and it has a ton of symbols and graphics in the library that aren’t actually used in the movie. Aside from just general organization, would it be worthwhile for me to remove them from the library before publishing, or does the swf compiler automatically disregard unused library items (they are not linked for AS, by the way)?
