Files are collections of data stored in a single container, often identified by their extensions. In Minecraft, data can be represented using wool blocks, where each block corresponds to a specific hex digit, allowing for the storage of bytes. A mapping was created to associate hex digits with wool colors, enabling data encoding and decoding within the game. An encoder script generates an "mcfunction" file for efficient block placement, while a decoder reads the wool matrix from the game world using the Amulet library. The process involves defining coordinates and dimensions for the wool matrix, and successful decoding reveals the original encoded message. This project demonstrates the versatility of data representation, though it is not intended for practical use.
