About .rad Files
RAD files are versatile and can serve different purposes based on their MIME type.
- Image (image/vnd.radiance): These files store Radiance HDR image data. They are used in 3D rendering and lighting simulation. Applications like Radiance or HDR image viewers open them.
- Text (text/plain): These RAD files contain Rexx-Adventure game source code. They are plain text files that can be edited with basic text editors. This format is popular among developers of adventure games.
- Audio (audio/x-mod): In this form, RAD files are modules for the Reality AdLib Tracker. They hold musical patterns and instrument data. Audio trackers such as OpenMPT can play or modify these files.
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.

FAQs
How do I open a .rad file?
The program you need depends on what kind of data the file contains. If it is a Radiance HDR image, you can view it with XnView MP or Adobe Photoshop. If it is a Reality AdLib Tracker music file, use an audio player like OpenMPT (Open ModPlug Tracker). For Rexx-Adventure source code, any text editor like Notepad or Notepad++ will work.
How can I convert a RAD image to JPG or PNG?
You can convert Radiance HDR images using image processing software like XnConvert or Adobe Photoshop. However, since .rad files are High Dynamic Range images, converting them to standard formats like JPG may require tone mapping to preserve the lighting details correctly.
What audio player opens RAD music files?
RAD audio files are FM synthesis modules created by the Reality AdLib Tracker. To play them on modern systems, you should use a dedicated tracker or module player such as OpenMPT or Schism Tracker. Standard media players like Windows Media Player usually cannot open this specific format without plugins.
Why does my .rad file open as text?
If your file opens in a text editor and shows readable code, it is likely source code for a Rexx-Adventure game. These files are plain text documents containing game logic and dialogue. You can edit them safely using basic editors like Microsoft Notepad or Sublime Text.
What are the MIME types associated with .rad files?
Because the extension is used for multiple formats, the MIME type varies. Radiance images use image/vnd.radiance, while the audio modules are often identified as audio/x-mod. The text-based game files are typically treated as text/plain. You can look up specific configurations at mime-type.com.
Can I edit a .rad image file?
Yes, but you need software that supports High Dynamic Range (HDR) editing. Adobe Photoshop allows you to edit Radiance files, often used in 3D rendering workflows to simulate realistic lighting. Free viewers like Luminance HDR can also handle these files for viewing and simple adjustments.
General 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.
