What is a NUT file?

Nut file extension has Squirrel Script file type, developed by Alberto Demichelis, which is associated with the "game files" category.

These are files with the source code in the Squirrel programming language. A NUT file is a script that serves as a plugin and extends program’s functionality or triggers scripted events in video games. The Squirrel object-oriented programming language is similar to JavaScript, Lua, and C++. Used mainly for video games, for example, Shadow Warrior, Simutrans, and Valve’s Portal 2 and Left 4 Dead 2. NUT files with the Squirrel source code are always small and rarely hit 1MB in size. NUT files with video are bigger than 1MB.
