What is a NUT file?

NUT files mostly belong to NintendoWare Resource Compressor. The NUT file extension is used in different contexts. It may be a part of a Nintendo game archive or a script file for the Squirrel programming language, and sometimes it acts as a container for multimedia data.
Nintendo Game Archives:

These files are created by the NintendoWare Resource Compressor. They store game resources like textures, audio, levels, and animations for systems such as the Wii U.

Squirrel Script Files:

Many games use NUT files to hold Squirrel scripts. These plain-text files control engine behaviors and game logic in titles like Left 4 Dead 2 and those running on the Source Engine.

Multimedia Containers:

On occasion, NUT files are used to bundle video or animation data. They can also incorporate compression methods such as GZIP.

FilExt.com notes: If you have a NUT file, first check its origin. If it comes from a Nintendo game, you may need tools designed for that system. If it is a Squirrel script, a text editor or Squirrel interpreter might work. Additional details can be seen on the Nintendo, Squirrel, and FFmpeg webpages.
