What are game files?
Game files are very important for any computer game. The game files are basically the files related to your video games and other games that you have installed on your computer system. These game files store all the essential data associated with a video or other game. The game data may include the game’s installation files, game ROMs, map files, character designs, dialogues, configurations, texture information, saved game progress, etc. It also includes the project files that developers have used in creating a video game.
Most commonly, the game files are saved in the following file extensions:
- GAM: It is a standard file format to store game “save” information which basically means saving the progress of a player in a game at a specific point of gameplay.
- DXT: This game file format is a generic format to store texture information in a compressed format using less disk space. It is also known as S3CT (S3 Compressed Texture) and BC (Block Compression).
- MAP: This game file format is used by most video games for debugging maps and other related purposes.
- ROM: These game files are used to save console-based video games on a PC. It is primarily used by Nintendo 64 games.
- VDF: VDF stands for Valve Data file. It is used by Valve’s Source game engine for saving the game’s metadata. It also stores data like resources, scripts, visualization elements, etc.
