There are 3 file types use the .TMD file extension:
1. MySQL Temporary Database File
Intermediate database file created by MySQL, an open source relational database program; contains information that helps MySQL complete database recoveries or conversion processes; created in the database directory where the .MYI, .MYD, and .FRM files are located.
TMD files can be created when the myisampack MySQL command is run. If the process is terminated before completion, the temporary TMD files might not be deleted. TMD files may also be created by other MySQL database operations.

2. Nintendo Title Metadata 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).
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.
