Wikis / Unreal Wiki / Legacy:Map File

A Map file is just like any other Unreal Engine file packages. Being a package they can contain all types of resources; the .unr file extension is merely a convention to denote "this package contains brushes and actors that make a playable map."

Check Antonio Cordero's website for a pretty thorough documentation of the Unreal package format and a Delphi unit that implements it.
