What is a MUSE file?

MUSE files mostly belong to Emacs by Free Software Foundation, Inc. MUSE is the filename extension of a text document created and/or edited in "muse-mode" using the Emacs Muse document authoring and publishing environment in Emacs editor. Emacs highlights directives, keywords, and URLs in various colors when the document being edited is assigned MUSE filename extension. "muse-mode" is typically used in creating web pages and scientific documents. Another type of MUSE file is a website project created by Muse no-/low-code web development environment. Muse was discontinued in March of 2020.

MUSE file format:

A file format defines how the data in the file is structured. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the MUSE files is as follows:
