.MSCZ, File

The mscz, file extension is most likely exclusively related to MuseScore music notation software and used for one of its default file types.

The .mscz, file contains backup of the MuseScore compressed music score file (.mscz).

These are created automatically and are saved in the same file folder as your normal MuseScore file.

How to open:

To open the file, rename the file by removing the comma and open it in MuseScore.

How to convert:

MuseScore supports other music score file formats and can save *.mscz, file to them.
