About .hdr Files
HDR files are used for storing high-dynamic range images and for containing header information in help systems.
Radiance RGBE Image Format: These HDR files use the MIME type image/vnd.radiance and store detailed light information. They capture a wide range of brightness values in a single image.
- Use case: High-dynamic range imaging in computer graphics and 3D rendering.
- Software: Applications like Adobe Photoshop and Radiance are known to open and edit these images.
- Key fact: They maintain accurate light and color details.
HotHelp Header: Some HDR files serve as header files for help documentation and use the MIME type application/octet-stream. They act as configuration components for help systems.

- Software: Help authoring and viewer tools may work with these files.
- Key fact: They contain binary data used to structure online or local help documentation.
Based on information from FilExt.com, HDR files serve distinct functions depending on the context, either enhancing 3D visuals or supporting help documentation systems.
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.
