A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .nhd Files
NHD files are hard disk images created for the North Star Horizon system.
They store an entire disk's data in a binary format.
- Backup: They keep a complete copy of a disk’s sectors and file system.
- Emulation: They are used with emulators to replicate legacy hardware behavior.
- Data Preservation: They help maintain and study old computing environments.
Specialized disk imaging or emulation software is typically required to open or manage these files.
According to FilExt.com, NHD files are primarily designed for North Star Horizon 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.

FAQs
What is an NHD file?
An NHD file is a hard disk image created for the North Star Horizon, a vintage microcomputer system. It stores a complete, bit-level backup of a hard drive, including the file system and data, primarily used for preserving legacy software and running it via emulation.
How do I open an NHD file on Windows or Mac?
You cannot open an NHD file with standard applications; you must use a specific emulator like the North Star Horizon Emulator or Solace. These programs simulate the original hardware and allow you to "mount" the .nhd file as a virtual hard drive to access its contents.
Can I edit the contents of an NHD file with a text editor?
No, opening an NHD file in a text editor will display unreadable garbled text because it contains raw binary data. The MIME type for these files is usually application/octet-stream, meaning they are meant to be read by machines, not humans. You should modify files within the emulated environment or use a hex editor.
How do I convert an NHD file to other disk image formats?
Conversion typically requires specialized tools designed for CP/M file systems or retro-computing disk utilities. Since NHD files are often raw binary dumps, they may be compatible with generic raw image formats (.img or .bin) simply by renaming the extension, provided the target emulator supports the specific sector layout.
Why does my computer not recognize the .nhd extension?
The North Star Horizon is an obsolete system, so modern operating systems do not have built-in associations for NHD files. To fix this, you need to install an appropriate emulator and manually load the file through the software's disk manager interface.
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.
