Dumb Question about Editor

[Coriolanus]

Okay, I've searched the forum until my eyes are forum blue. I'm now using the mac version and love it, but....

I cannot for the life of me find the data files to be edited with the HLEditor. I could do this no problem on the PC but in the 'pathfinder' folder (the game system I'm using) I just can't find the files?? Anybody tell me where they are? Are the in the .pkg files? If so, since these don't seem to be able to be opened, how do you edit a file?"

All I'm trying to do is make a change to a trait that I don't like.

Anyone?

Thanks, all.
