What is an MSS file?

MSS files mostly belong to Materials Studio. An MSS file is not a single file type but a label used for files created by different software.
For one use, it is a Materials Studio file that uses a Microsoft Compound format. This file holds simulation and material data created by Materials Studio software (from MTS TestWorks). You can learn more at MTS.
In another scenario, an MSS file can be a game save file. It stores game progress for titles like MechWarrior 5: Mercenaries and Magic: The Gathering. For details on this usage, see this link.
Finally, some MSS files work as a MuseScore style sheet using the XML format. They hold layout and styling details for music scores. Visit MuseScore for more information.
Key points summarized by FilExt.com:

File content and structure change based on its purpose.

It may use a compound format, plain XML, or even other formats.

Proper opening requires the correct software, such as simulation tools, the game itself, or MuseScore.

Viewing in a text editor can reveal XML data in style sheets.
