About .mcm Files
MCM files are compressed archives that bundle multiple files into one binary container. The MIME type application/octet-stream indicates that the file holds raw binary data, often used when no more specific type applies.
They reduce file size and help distribute data efficiently. The archive can hold anything—from software components to game assets. The exact content depends on the creating software.
- Software installers: Bundling multiple installation files.
- Game asset packages: Combining graphics, audio, and other resources.
- Data backup archives: Compressing files for secure storage.
Some archive managers like 7-Zip or WinRAR might open these files. In some cases, you may need dedicated or specialized software.
Based on information from FilExt.com, MCM files are versatile compressed containers widely used for packaging and transferring diverse data sets.
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.
