What is a WIN File Type?

The file type is l' one of the many active packages from which a game developer can choose to support the distribution of his game. The package is designed to protect against modifications by users attempting to alter the gameplay.

Players using the WIN file type can find the WIN file in the same directory as the .EXE game file. Examples of games using the WIN file developed by GameMaker Studio include Rivals of Aether, IMSCARED, Deltarune and Undertale.
