About .sad Files
SAD files are binary disk image files used to store data from SAm disks.
They hold an exact copy of a disk’s content at the sector level. The application/octet-stream MIME type shows that the file contains raw binary data.
- Main use: Capturing complete disk images from SAm systems.
- MIME type: application/octet-stream indicates a generic binary file.
- Other uses: Archiving, backup, and disk emulation.
- Software: Specialized disk imaging tools or emulators are needed to open or edit 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
What is a .sad file?
A .sad file is a disk image created from Sam Coupé floppy disks. It contains an exact, sector-level copy of the original disk's data, primarily used for archiving vintage software or running games on emulators like SimCoupe.
How do I open a .sad file on Windows or Mac?
You cannot open these files with standard operating system tools; you must use a Sam Coupé emulator. Download SimCoupe, launch the application, and load the .sad file into one of the virtual floppy drive slots to run the program contained within.
Can I convert .sad files to other disk image formats?
Yes, you can use the SamDisk utility to convert .sad files to other formats like .dsk or .mgt. SamDisk is a specialized command-line tool designed to handle the specific geometry and headers of Sam Coupé disk images.
Why is the MIME type for .sad files listed as application/octet-stream?
Because .sad files are binary disk dumps without a globally standardized media type, they are often classified under the generic application/octet-stream MIME type. This indicates to web servers and browsers that the file should be treated as a binary stream requiring an external application to open.
Can I edit the contents of a .sad file?
Direct editing is difficult without specialized tools. You typically need to mount the image in an emulator to modify files within the virtual disk, or use a hex editor if you understand the raw binary structure of the file system.
How do I write a .sad file back to a physical floppy disk?
To restore a .sad image to a real floppy disk, you need a PC with a floppy drive controller capable of writing non-standard formats and the SamDisk utility. Note that standard USB floppy drives often cannot write these specific vintage formats due to hardware limitations.
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.
