Which MIME types are related to file extension ".sps"?
The .sps file extension is associated with 2 MIME types:
text/x-scheme, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .sps Files
SPS files are files that can serve two different purposes based on their MIME type.
- Text-based SPS files: These use the MIME type text/x-scheme and store code written in the Scheme programming language. They are plain text and can be opened with editors like Notepad++, Sublime Text, or VSCode. Scheme interpreters such as Racket or Guile can execute the code. According to FilExt.com, this is a common use for SPS files.
- Binary SPS files: These use the MIME type application/octet-stream and contain Spectrum 512 compressed (or “smooshed”) bitmap image data. They are binary files not meant to be read in a text editor. Specialized programs, like Spectrum emulators or dedicated graphic converters, are typically needed to view or edit the image 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.

FAQs
What is an .sps file?
An .sps file typically serves one of two purposes: it is either a source code file written in the Scheme programming language, or a compressed bitmap image created by Spectrum 512 for old Atari ST computers. To determine which one you have, try opening it in a text editor; if it is readable text, it is code.
How do I open an .sps file that contains code?
If the file contains Scheme source code, you can view and edit it with any text editor, such as Notepad++, Visual Studio Code, or Sublime Text. To execute the code, you will need a Scheme interpreter like Racket, Chez Scheme, or Guile.
How can I view a Spectrum 512 .sps image?
Spectrum 512 images are binary files that modern image viewers cannot open natively. You can use specialized tools like RECOIL (Retro Computer Image Library) or XnView to view these files or convert them into standard formats like PNG or JPG.
Why does my .sps file look like random symbols in Notepad?
If you see garbled characters or "gibberish," you are likely trying to view a binary Spectrum 512 image in a text editor. These files are not text-based and often use the generic MIME type application/octet-stream; you must use a compatible image viewer instead.
How do I convert an .sps file to PDF?
For Scheme code files, you can simply "Print to PDF" from your text editor. For Spectrum 512 images, you should first convert the image to a standard format like PNG using XnView, and then convert that image to a PDF if necessary.
What is the MIME type for .sps files?
Scheme source files generally use the MIME type text/x-scheme or text/plain, while binary Spectrum images often fall under application/octet-stream. You can verify specific type configurations on mime-type.com.
General 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.
