application/x-ms-msm, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .msm Files
MSM files are primarily used as Windows Installer Merge Modules or as MegaStation MIDI modules.
For the Windows Installer Merge Module type (application/x-ms-msm):
- Main Use: They package shared installation components into a CAB archive.
- Functionality: These modules merge into larger installer packages. They standardize the installation of common features across different software products.
- Software: Tools like Microsoft Visual Studio, WiX Toolset, and Advanced Installer create and integrate these files.
- Reference: According to FilExt.com, they are vital for managing reusability in installations.
For the MegaStation MIDI module type (application/octet-stream):
- Main Use: They store MIDI sample data or instrument definitions.
- Functionality: These files support audio applications, particularly in music composition and editing.
- Software: MIDI editors and music sequencers are used to open or manipulate these files.
MSM files are not meant to run on their own. Their role depends on the context—either enhancing software installation routines or providing data for music applications.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
