Directory problem

hi, here’s the folders structure of my files:
I have a folder named OMG
inside that folder there’s another folder called sf1 and sf2
inside sf1 folder I have a .as file named sf1.as, and also another folder called box1
inside box1 I have box.as/.fla/.swf

so my question is:

  1. if I want all my .as files inside the OMG folder to share the same package how should I name the package? because no matter what I try it returns an error saying that the package name doesnt reflect the location of the file etc…

  2. how should I call the class inside sf1.as and box.as? Something like OMG.sf1.etc something?

  3. how do I access the file sf1.as inside box.as?

thanks
