A CDT file is a game level created by Super Mario Maker, a Super Mario level creator available for the Wii U. It contains binary data specifying a level's layout, including placed blocks, enemies, and other objects, settings, and metadata. While CDT files are meant to be opened only in Super Mario Maker, some modders have created utilities that can read the data CDT files contain.

Super Mario Maker is a Wii U game that allows players to create and play their own Super Mario levels. Players can also publish their levels online so others can play them.

Levels created using Super Mario Maker are saved as CDT files. These files include level data, such as the level's game mode, theme, and layout, and metadata such as the level's creation date and time.

CDT files are meant to be opened in Super Mario Maker. However, players have created some utilities, such as SMM Course Viewer (Web) and Mario Unmaker (multiplatform), that allow them to view the level a CDT file contains outside Super Mario Maker.
