What is a TMD file?

A TMD file contains title metadata used to verify the integrity and run Nintendo 3DS, Wii, and WiiU games. It stores metadata about the file that contains the actual game data, such as an APP, 3DS, or CIA file, and is referenced to decrypt and verify the contents of the game data file to launch the game. TMD files are typically distributed by Nintendo Update Servers (NUS).

More Information

TMD files may store varying metadata depending on the console the game is created to run on. For example, a TMD file for a WiiU game contains the required WiiUOS version, whereas a TMD file for a 3DS game will not include that information.

Most 3DS, Wii, and WiiU gamers will not encounter a TMD file since it is referenced by the Nintendo console in the background when a game is launched. However, gamers who want to emulate a game on their computers will most likely see the TMD file (along with a TIK and CERT file) accompanying the main game data file.

What is a TMD file?

TMD file open in World Machine

World Machine allows developers to procedurally generate realistic-looking 3D terrain for use in video games and other applications. To generate terrain, a developer links a series of World Machine devices together. These devices control how World Machine shapes the developer's terrain. Devices can be used to create new terrain, edit existing terrain, and export terrain to different file formats.

If a developer wants to save an in-progress or finished World Machine project, they can select File → Save World from the program's menu bar. This saves the developer's current world as a TMD file.

When a developer selects Build World from World Machine's menu, World Machine uses the device tree the developer has assembled to generate terrain. World Machine will also export the terrain in additional file formats, if the device tree includes output devices configured to export terrain.

NOTE: To view the devices a TMD file contains, view the file in World Machine's Device Workview. To view the terrain those devices generate, view the file in the Layout or 3D View.

How to open a TMD file

You can open a TMD file in World Machine (Windows). To do so, select File → Open World... from World Machine's menu bar. Then, navigate to and open your TMD file.
