The XAN format belongs to the Worms series from Team17. In Worms 3D and Worms 4 Mayhem, the file provides the 3D data needed to display a game map and its associated models.
This is a game-specific format for the Microsoft Windows versions of Worms 3D and Worms 4 Mayhem. It is a legacy format tied to those games rather than a general-purpose 3D model or map format.
Open a .xan file through the Microsoft Windows version of Worms 3D or Worms 4 Mayhem that uses it. The file is intended to be read by the game and normally cannot be opened meaningfully as a standalone file in a standard viewer.
There is no standard conversion method for a Worms 3D map file. The XAN format is game-specific, so it should generally be kept with the game files and used by Worms 3D or Worms 4 Mayhem rather than converted to another format.
