About .msn Files
MSN files are mission files used in classic video games. They come in two main types based on their MIME type.
- text/plain – This version is a plain text file. It stores mission details for Descent Mission. You can open these files with any text editor like Notepad.
- application/octet-stream – This is a binary file. It contains saved mission data for Project: Space Station. They require the specific game software to view or edit the mission.
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.

FAQs
What is a .msn file?
A .msn file is typically a mission data file used by classic video games like Descent or Project: Space Station. These files contain essential level information, such as map layouts, enemy placement, and mission objectives, which the game engine reads to load a specific stage.
How do I open a .msn file?
If the file is a Descent mission, it is formatted as plain text and can be opened with any text editor like Notepad, TextEdit, or Notepad++. If the file belongs to Project: Space Station, it is a binary file that cannot be viewed manually and must be loaded directly by the game software or a compatible emulator.
Can I edit a .msn file?
Yes, but only if it is a text-based mission file for the game Descent. You can modify level parameters using a standard text editor, provided you follow the specific scripting syntax required by the game engine. Binary .msn files (MIME type application/octet-stream) are not human-readable and should not be edited manually to avoid corruption.
Why does my .msn file look like random characters?
If opening the file in a text editor reveals garbled characters, it is likely a binary file used by Project: Space Station. Unlike the text-based Descent files (text/plain), these binary files contain compiled data that only the game executable can interpret correctly.
Is the .msn extension related to Microsoft Network?
Generally, no; in the context of file management, .msn usually refers to the game mission files described above. While "MSN" is a famous acronym for Microsoft Network, the service typically uses different file extensions for its software and logs, making a direct association unlikely for this specific extension.
How do I install a custom .msn mission for Descent?
To play a custom mission, place the .msn file into the main installation directory of the Descent game. Once the file is in the correct folder, launch the game and look for an option to load a "Custom Mission" or "External Level" from the main menu.
General 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.
