A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .idf Files
IDF files are used for defining MIDI instrument settings and for storing iCEDraw vector graphics data.
They have dual roles based on their MIME types.
- MIDI Instrument Definition: The MIME type application/x-riff shows that some IDF files use the RIFF container format to store MIDI instrument information. This data is used by music production and digital audio software to configure instruments.
- iCEDraw Files: The MIME types application/octet-stream and image/x-icedraw indicate that other IDF files contain graphic or diagram data created by the iCEDraw application. These files are handled by software designed to open and edit vector drawings.
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.
