About .sid Files
SID files are a varied file type that can hold different kinds of data.
- Audio: Some SID files contain chiptune music for the Commodore 64 SID chip. MIME types like audio/prs.sid, audio/x-sid, and audio/x-psid indicate these files store digital tunes. They are played with specialized applications such as Sidplay or even VLC when configured properly.
- Image: Other SID files use the MrSID format. MIME types such as image/x-mrsid-image, image/x-mrsid, and image/x.mrsid refer to these high-compression, high-resolution images. They are mainly used in geographic information systems (GIS) and can be opened with software like ArcGIS, Global Mapper, or GDAL.
- Text: A SID file may also be plain text as indicated by the text/plain MIME type. In these cases, the file serves as Sonnet Input Data used in specific text-processing or simulation tasks.
According to FilExt.com, the MIME type attached to a SID file tells you which kind of content it holds and what software is needed to handle it correctly. Each variant uses simple binary or plain-text data to achieve its purpose, whether it’s recreating classic SID tunes, storing compressed geospatial images, or holding specialized text data.
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.
