it is good when you have libraries, included files, scripts and plain vanilla html pages to devise some naming convention. Lots of people find it much easier to manage the files that way.
It really doesn't matter, having no system and sticking with that is as much a system as any other.
one note on included files though if there is php code in them
they should use extensions that are php parsed or they should be stored outside of the web root so they can't be called directly in a browser so that your code is not exposed.
