About .gmx Files
GMX files are XML‐based files defined by the MIME types application/vnd.gmx and text/xml. They follow a structured format that many vendor applications use to store and exchange data.
- XML Structure: Their content uses XML markup, making them human‐readable and easy to parse.
- Vendor-Specific Format: The application/vnd.gmx MIME type indicates a specialized format created by a specific developer or company.
- Configuration/Data Storage: They are often used to save settings, project data, or metadata in supported programs.
- Data Exchange: Being based on XML, they allow for platform-independent data sharing between applications.
GMX files can be opened and edited with any basic text editor like Notepad or Notepad++, and dedicated XML editors (for example, Microsoft XML Notepad) can provide additional structure visualization. The intended software from the vendor may also offer extra features for full functionality.
Based on information from FilExt.com, this file type leverages a common XML structure while integrating custom data definitions, making it practical for applications that need flexible and easy-to-read storage of complex information.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

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 can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
