What is a .W3X file?
W3X is a Warcraft III: The Frozen Throne map. Created with Blizzard’s World Editor.
- Did you know
- Custom W3X maps gave rise to the MOBA genre, including the original DotA.
- The W3X format extended the older Reign of Chaos .w3m for the Frozen Throne expansion, sharing the same MPQ-with-header structure.
- Like its predecessor it is an MPQ archive scripted in Blizzard’s JASS2 language and edited in the World Editor.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .W3X is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .W3X file
- Drag a .W3X file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
