What is a GMA file?

The GMA file format is primarily associated with Garry’s Mod, a sandbox video game that allows users to manipulate objects and create their own game modes. Here’s a breakdown of what the .gma format entails:

Key features of .gma files include

  1. Purpose: GMA files are used for storing game content, such as add-ons, mods, and other custom assets for Garry’s Mod.

  2. Compression: The .gma file format is essentially a compressed archive, often using a variation of the ZIP format. This allows multiple files (like models, scripts, and textures) to be packed into a single file for easier distribution and installation.

  3. Contents: When you extract a .gma file, you typically find various file types, including:

    • Model files (e.g., .mdl)
    • Texture files (e.g., .vtf)
    • Sound files (e.g., .wav)
    • Lua scripts (for custom game logic)

  4. Creation and Usage: Users can create .gma files using the Garry’s Mod Addon tool, which facilitates packaging custom content for sharing within the community. Players can then install these add-ons by placing the .gma files in the appropriate directory.

  5. Compatibility: While .gma files are specific to Garry’s Mod, they may also be used in other Source engine games, as Garry’s Mod is built on the Source engine.
