Which MIME types are related to file extension ".c"?
The .c file extension is associated with 5 MIME types:
text/x-c++src, text/x-c, text/x-csrc, image/x-xpixmap, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .c Files
C files are text-based files that store source code written in the C programming language.
They contain instructions that must be compiled to build executable programs.
The most common MIME types are text/x-c and text/x-csrc, which denote plain text with C code.
Sometimes, you might see text/x-c++src if the file contains syntax similar to C++ or is misclassified.
The application/octet-stream MIME type appears when the file is treated as generic binary data.
On rare occasions, the MIME type image/x-xpixmap may apply if the file is used to define an X PixMap image, a format often used for icons in Unix-like systems.
- Primary Purpose: To hold human-readable C source code for development.
- Common Tools: Opened and edited with text editors like Notepad++, Visual Studio Code, Sublime Text, or IDEs such as Code::Blocks and Visual Studio.
- Compilation: Processed by compilers such as GCC or Clang to create executable software.
- Alternate Use: Occasionally, to store X PixMap data as text for image representation.
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.
