An MCMETA file is an animation configuration file read by Minecraft, a popular game where the user breaks and places blocks in order to build structures and explore the virtual world. It contains animation information used to create the look of the Minecraft world.

The pack.mcmeta file accompanies each animation in the game. To create this file, you can use a basic text editor like Notepad or Notepad++. Editing this file allows you to customize your Minecraft experience. A line from an MCMETA file may appear as follows: { "animation": {"frame time"; 8} } NOTE: Minecraft references the MCMETA file, it is not meant to open it.
