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

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

application/x-koan is a custom MIME type. It signals that the file holds data from SSEYO Koan software. This software was designed to create interactive presentations and multimedia projects.

Files using this type store presentation details, animation sequences, and configuration data. They are tailored for projects with dynamic, visual, and textual components.

Common file types associated with this MIME type include SKP, SKD, SKM, and SKT. These file types open only with the specific presentation software that supports the Koan format.

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.
