Which MIME types are related to file extension ".cdr"?
The .cdr file extension is associated with 3 MIME types:

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .cdr Files
CDR files are mainly used for CorelDRAW vector graphics. They store design data in a compressed binary format with the MIME type application/x-coreldraw.
They can also be used as disk image files. This format follows the ISO9660 standard. In this use case, the MIME type is application/x-iso9660-image. Such images mimic the structure of a CD or DVD and are opened by disk mounting or burning tools.
A third use is for specific game data. In this case, the MIME type application/octet-stream designates a generic binary file. For example, some Team F1 Circuit game data is stored in CDR files and requires the game software to open or edit them.
- CorelDRAW Drawings: Maintain vector art, illustrations, and designs. Open them with CorelDRAW.
- Disk Images: Serve as exact copies of CD/DVD file systems. Use disc tools like Daemon Tools or ImgBurn.
- Game Data: Hold specialized binary information for games such as Team F1 Circuit. Only the game or compatible tools can read them.
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.
