What is MIME type "application/vnd.clonk.c4group"?

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

application/vnd.clonk.c4group is a vendor-specific MIME type. It tells your system that a file is a packaged group used by Clonk software.

This type acts as a container for all game assets. The format bundles resources like images, sound files, scripts, and level data into a single file. Files with this MIME type include formats such as C4D, C4P, C4G, C4F, and C4U.

Main purpose: Organizing and packaging all the needed game assets for the Clonk engine.
Usage: Bundling resources to ensure the game loads smoothly and remains consistent.
Format style: Works like an archive that contains several related files in one package.
Benefit: Simplifies distribution and updates by keeping all related assets together.

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.
