Which MIME types are related to file extension ".gir"?

The .gir file extension is associated with 2 MIME types:

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

About .gir Files

.GIR files are used in two distinct ways.
Most commonly, they are text/xml files that hold GObject Introspection metadata. This XML data describes the classes, methods, and properties of software libraries. It lets programming languages like Python, JavaScript, and Vala access functions from GNOME-related projects.
Alternatively, some .GIR files are application/octet-stream binaries. In this case, they capture movie data for the Gens Plus! emulator. These binary files record gameplay sessions and are used only by specialized tools.

GObject Introspection Data: XML files for binding libraries.
Used in GNOME projects and GTK+ applications.
Movie Capture Data: Binary files from the Gens Plus! emulator.
Require appropriate software to view or edit.

You can open XML-based .GIR files with text editors like Notepad++ or Visual Studio Code. For binary movie captures, use the Gens Plus! application or a compatible utility.
Based on information from FilExt.com, the purpose of a .GIR file depends on its content.

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.
