# What is a `.mfa` file?

A .mfa is the file format used for Clickteam Fusion 2.5 projects. It is a single file that stores images, sounds, events, and anything else the project needs (with a few exceptions), making it easy to store and distribute.

Note

This file structure is only accurate to the latest version of Clickteam Fusion 2.5, .mfa files from older versions may have differences, and .mfa files from Multimedia Fusion 2 are not the same as the listed structure.
