Which MIME types are related to file extension ".sch"?
The .sch file extension is associated with 7 MIME types:
text/xml, text/x-scheme, application/x-eagle-schematic, application/x-kicad-schematic, text/plain, application/octet-stream, application/x-scheme.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .sch Files
SCH files are used for many purposes.
They can store electronic schematics, code, or configuration data.
- EAGLE Schematics: These files often use an XML format. MIME types like text/xml and application/x-eagle-schematic indicate they hold circuit designs made in Autodesk EAGLE (v6+).
They help create and document how electronic components connect. - KiCad Schematics: When the MIME type is application/x-kicad-schematic, the file holds a diagram from the KiCad EDA suite.
It is used for designing and testing circuit layouts. - Scheme Scripts: With MIME types such as text/x-scheme and application/x-scheme, these files contain code written in the Scheme language, a dialect of Lisp.
They serve as program source files for script execution. - Proton Language Schema: The text/plain MIME type shows that the file might hold schema information related to the Proton language.
- GFA Raytrace Bitmap: The application/octet-stream MIME type is used when the file contains compressed high-resolution bitmap data for GFA Raytrace images.
Different software like Autodesk EAGLE, KiCad, or Scheme interpreters can open 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.

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.
