Just for curiousity sake, what exactly is the difference between folders and packages?
Because I find I can use them pretty much interchangeably. Does anyone know what exactly the difference is? It seems the convention is to place classes inside packages.
There isn’t one. For all intents and purposes I would say that a package is a folder with a special purpose–to contain class files.
This isn’t unique to Flex or ActionScript, most programming languages use the same approach and nomenclature.
