What is a BWV file?

A BWV file is an audio file used by a Super Mario Maker course. It contains the course's sound effects and background music. BWV files are saved in a proprietary file format and not meant to be opened outside Super Mario Maker.

More Information

Super Mario Maker is a Wii U game that allows players to create, play, and share their own Super Mario courses. These courses are typically saved within course-specific directories (named course###) on the hard drive of a player's Wii U.

Each course's directory includes a .CDT file, two .TNL files, and a BWV file. The BWV file contains the background music and sound effects that play in that course. While most players will never encounter Super Mario Maker's BWV files, modders and other Super Mario Maker enthusiasts may encounter BWV files while examining save data they've extracted from their Wii U.

Common BWV Filenames

sound.bwv - The default name Super Mario Maker assigns BWV files.

How to open a BWV file

BWV files are not meant to be opened. Super Mario Maker loads and plays audio from a course's BWV file when a player plays that course.
