What is MIME type "application/x-endnote-style"?

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

application/x-endnote-style is a MIME type for files that control citation formatting. It is mainly used by EndNote style files, such as ENS.

These files give instructions to the EndNote software. They set rules for how citations and bibliographies appear in academic texts. They define punctuation, order, and style details.

Citation Formatting – Files determine the layout and presentation of references.
Document Consistency – They ensure all citations follow a uniform style.

The MIME type is not standard in external registries but is recognized by the EndNote application. For more details on MIME types, visit IANA media types.

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.
