What is an MM file?

An MM file contains a "mind map," which is a visual diagram that consists of text, nodes, branches, shapes, and icons that represent ideas. It may be created by a variety of "mind-mapping" programs, such as FreeMind and Freeplane. MM files are often used for organizing ideas when brainstorming, researching topics, tracking projects, and taking notes.

FreeMind is designed to help you visually organize ideas. You can create maps that consist of ideas placed in nodes that can be connected to other nodes and images. FreeMind is an open source program and is available as a free download.

It is used to manipulate digitized signals and other signal collection and processing systems data. It's primary mode of operation is responding to text commands, which makes the use of MM macro files important.
