Minecraft File Extensions

A file extension is the series of letters after the period in a name of a computer file. File extensions specify the program or programs the file is associated with. In Minecraft: Bedrock Edition, many extensions begin with '.mc,' as detailed below.

.mcaddon

.mcmeta

.mcpack

.mcproject

• .mcworld files can be imported into Editor, at which point they are converted to an .mcproject.
• When an .mcproject is exported as an .mcworld, Editor extensions are removed.

.mcstructure
