What is MIME type "application/x-geogebra-file"?

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

application/x-geogebra-file is a MIME type used for GeoGebra worksheets.
It tells your computer or browser how to handle a file created by GeoGebra software.
GeoGebra files are interactive math worksheets. They store elements like dynamic geometry, algebraic expressions, and calculations.
This format lets users explore math problems visually and interactively.

Interactive Math Exploration: Files support dynamic geometry and algebra, letting users manipulate mathematical figures.
Educational Use: Widely used in classrooms and self-study for interactive learning.
Data Consolidation: The file may compress several resources, such as diagrams, equations, and multimedia components.
Software Integration: Opens directly in GeoGebra software, which is available on multiple platforms.

GeoGebra worksheets usually have the file extension GGB.

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.
