There is only one file type that uses the .MAPLET extension:
Maplet World File
World map created by Maplet, a free program used to create 3D worlds; stores the layout of the world as well as textures and lighting information; can be exported to a .B3D file, which can be used to load the world in Blitz3D game making software.
NOTE: Maplet is no longer developed or available for download.
