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

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

application/x-blorb is a MIME type for a container file format. It bundles code with multimedia assets like images and sounds used in interactive fiction.

Developers use Blorb files to keep all game resources in one package. This helps in distribution and consistency when running an interactive story. Typical file types include GLB, BLB, GBLORB, ZLB, BLORB, and ZBLORB.

Resource Bundling: Combines game logic and media in one file.
Simplified Distribution: Easier to share complete interactive fiction games.
Compatibility: Recognized by many interactive fiction engines.
Experimental Tag: The "x-" prefix shows it is not a standard but widely used format in its niche.

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.
