A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .rgh Files
RGH files are binary files that store a rough bitmap image.
They use the MIME type application/octet-stream, which is a generic tag for binary data.
The note "(ZZ ROUGH bitmap)" indicates that the file holds raw or preliminary bitmap data.
- Main Use: Serving as a container for rough image data.
- Functionality: Acting as a temporary format for bitmap pictures or rough drafts.
- Software Support: They may be opened with specialized graphics tools, image editors, or even hex editors that can read binary 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
What is an .rgh file?
An .rgh file is a binary file that typically stores a "rough bitmap" image, often representing raw or preliminary graphical data. These files are generally used in niche software development environments or older graphics applications to hold temporary image drafts.
How do I open an RGH file?
Because this is a specialized format, standard image viewers like Windows Photos or Preview usually cannot open it. You may need to use the specific software that created the file, or attempt to import it using advanced image editors like GIMP (using the "Raw Image Data" import feature) or a hex editor.
Can I convert an RGH file to JPG or PNG?
Direct conversion is difficult unless you have the original software, but it is possible if the file contains standard raw pixel data. You can try using command-line tools like ImageMagick or opening the file as raw data in an editor and then "Export As" a standard image format like JPEG or PNG.
What MIME type is associated with RGH files?
RGH files are typically served with the generic MIME type application/octet-stream. This general-purpose tag indicates binary data that requires an external application or manual intervention to interpret. You can learn more about this category at the application/octet-stream page.
Why does my computer say it cannot open this file?
The .rgh extension is not standard in modern operating systems like Windows or macOS, so no default program is associated with it. To open it, you must right-click the file, select Open With, and manually choose a compatible application or a hex viewer.
Are RGH files dangerous?
RGH files usually contain bitmap image data and are not executable, meaning they are generally safe. However, because they use the generic application/octet-stream type, it is always best practice to scan unknown files from the internet with antivirus software before attempting to open them.
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.
