What is MIME type "application/x-msterminal"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-msterminal is a MIME type used for files related to terminal sessions. It signals that the file holds command-line data or session configuration rather than conventional text, image, or video content.

Files with this MIME type usually work with terminal programs or command-line emulators. They can contain instructions, settings, or connection details that help launch or manage a terminal session. This is common in specialized or legacy PC environments. The type is marked with the prefix x-, which tells you it is non-standard or vendor-specific.

Main use: Launching and configuring terminal or command-line sessions.
Other uses: Storing session details like commands and connection parameters for remote or local operations.
Key fact: The MIME type targets files that control terminal behaviors rather than display content like images or texts.

This MIME type is linked with files such as TRM. For a broader view of MIME types and their purposes, visit Wikipedia on MIME.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
