The .#map file format (stored in rage::fwMapDataStore) is a PSO/RSC-style format expecting a CMapData (project-specific, inherits from rage::fwMapData) root element.
Formerly, this would be placed in a .#pl file. .#map is also known as .imap in North naming conventions.
The #map format has the following structure:
