About .wmp Files
WMP files are files that can serve two distinct purposes. They may contain Infinity Engine World Map (v1.0) data or use the JPEG XR image format.
For the game map case, these files use the MIME type application/octet-stream. This format holds binary data specific to certain role-playing games built on the Infinity Engine. It stores map details used by the game and can be opened by the game engine or specialized map editors.
In the image scenario, WMP files use the MIME types image/jxr and image/vnd.ms-photo. They implement the JPEG XR compression method. This method improves image quality and compression over older standards. Many image viewers and editors—such as Windows Photo Viewer or apps in Microsoft Office—support JPEG XR.
- Infinity Engine World Map (v1.0): Binary format for game maps; opened by the game engine or modding tools.
- JPEG XR Image: High-dynamic-range images with enhanced compression; viewable with image software supporting JPEG XR.
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.
