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

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

The MIME type application/x-xmind marks files used by the mind mapping tool XMind Pro. It tells your system and apps to treat these files as structured mind maps. These maps contain nodes, links, and notes that visually organize ideas.

This MIME type is key for software to open and process content correctly. The file is typically saved with the extension XMIND.

Brainstorming and idea organization – It formats creative maps for planning projects.
Project management – It supports outlining tasks and visual strategies.
Learning and presentations – It aids visual explanations and structured notes.

The MIME type helps maintain compatibility between software and files. More information is available on the XMind website.

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.
