An MC file is a pattern file used by Conway’s Game of Life to store very large or complex patterns. It stores data in the Macrocell (MC) format, which saves cell-state patterns as reusable blocks rather than listing every cell, making the file much smaller and faster to load than simpler Life (.LIF) formats.

The Macrocell format was designed for performance and scalability, especially when working with patterns that contain repeating structures or vast empty areas. Instead of explicitly storing each live cell, an MC file defines blocks that can reference other blocks, creating a tree-like structure.

Simulation software expands these blocks dynamically as needed during viewing or simulation. This makes the format well-suited for large Life patterns, such as spaceships, oscillators, breeders, and engineered constructions, which would be difficult to store in simpler formats.

POZNÁMKA: Compared to older formats, such as LIF or .RLE, Macrocell is designed for speed and memory efficiency rather than human readability.

You can open MC files with Golly, a popular open-source cellular automaton simulator. The simulator provides native support for the Macrocell format and allows users to view, edit, and simulate patterns interactively.
