I've done some searching and I couldn't find anything, I'm looking for the file structure of wordpress for example: wp-admin would contain bla2 (with explanations of what the files would do)...

FYI I'm now looking to edit the pages' code, not just the themes' code. But I wanna know what each of the files do(well not that specific), cause I'm greedy. Please ignore the last part...
