.MCR File Extension

Game file used by Minecraft, a sandbox block construction game; contains a 32x32 region of a Minecraft world; named as r.x.z.mcr, where "x" and "z" specify the region's coordinates; used for saving "chunks" of the world.

The "x" and "z" portions of the region filename can be derived by dividing the chunk coordinates by 32. For example, the (64, 0) region has the filename r.2.0.mcr.

NOTE: MCR files were introduced with the Beta 1.3 version of Minecraft and were later replaced by the "Anvil" format (.MCA files). Prior to the MCR format, .DAT files were used.
