Opening MUS files

Did your computer fail to open a MUS file? We explain what MUS files are and recommend software that we know can open or convert your MUS files.

What is a MUS file?

Files that contain the .mus file extension are most commonly associated with music notation files that have been created by the Finale software application, which is MakeMusic's music notation program.

MakeMusic is popular for their music notation software, which allows for the composing and publishing of music files and information. The MUS files that are used by their programs save data in the MIDI file format.

MUS files are very similar to MID files, but they contain additional information that can only be read by the MakeMusic notation software. The MUS files contain music notation details, but they do not contain any actual audio data.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
