A save file in games is a digital file that stores the progress, settings, and data of a player's game. This file allows the player to resume the game from the point where they last saved, rather than starting over from the beginning. Save files typically include information such as the player's position in the game, completed missions or levels, acquired items, character stats, and other game-related data.

Save files can be automatically created by the game at certain checkpoints, or they can be manually created by the player at specific points in the game. Depending on the game, save files can be stored locally on the player's device, in the cloud, or on external storage devices.
