What is a .DAT_MCR file?
The .DAT_MCR file is a special type of file used by the game Minecraft, which is a game where you can build and explore in a 3D world. This file is a backup of another file called level.dat. It is created automatically by the game when it updates from an old way of saving game worlds, known as the "Region" (.MCR) format, to a newer way called the "Anvil" (.MCA) format.
To open a .DAT_MCR file, you need to use the game Minecraft itself, made by a company called Mojang. This is because the file is specifically designed to work within the game.
More information about this file type includes that if you ever want to go back to the older way your game world was saved, you can use the .DAT_MCR file to restore the level.dat file to its previous state. This might be useful if you prefer how things were before the update. It's important to note that the change to the Anvil world format first happened in a version of Minecraft called Snapshot 12w07b.
