What is a W3X file?

Files that contain the .w3x extension are created with the Warcraft III: The Frozen Throne computer application. Warcraft III is a role-playing video game that is published by Blizzard Entertainment.

The W3X files contain the game maps and scenarios that have been created for use within the Warcraft III video game. Some of the information that is contained in the W3X files can include map information such as region details, terrain info and other map objects.
