A MCTEMPLATE file contains a template of a world used in Minecraft, a popular block-building game. It stores multiple files, such as .DAT, .TXT, .PNG, .JSON files compressed with ZIP compression. MCTEMPLATE files are similar to .MCWORLD files and are used to save Minecraft worlds that are commonly used.

MCTEMPLATE files are typically created by a user when he zips the world files into one .ZIP file then renames the extension from ".zip" to ".mctemplate". Since MCTEMPLATE files are saved in a ZIP format, they can be expanded using a Zip decompression utility. MCTEMPLATE files are only supported by the Windows and Android versions of Minecraft. Minecraft on other platforms does not support MCTEMPLATE files. Instead, .MCPACK files are used.
