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.

How do I open a .spayd file?
You typically do not "open" these files like a document; instead, you import them into compatible internet banking software or accounting tools. If you simply need to view the raw payment data, you can open the file with any basic text editor like Microsoft Notepad or Apple TextEdit.
How does a .spayd file relate to QR codes?
The data inside a .spayd file is often encoded into a QR code to allow users to scan and pay instantly via mobile banking apps. The string format ensures that the banking app automatically fills in the recipient, amount, and payment reference without manual typing.
Can I create or edit a .spayd file manually?
Yes, because the file uses a simple text-based format, you can edit it using a code editor like Notepad++ or Visual Studio Code. However, you must strictly follow the Short Payment Descriptor syntax (e.g., SPD*1.0*ACC:...) to ensure banking systems accept the file.
How should a server be configured to serve .spayd files?
Web servers should be configured to serve these files with the MIME type application/x-shortpaymentdescriptor. Correct configuration ensures that when a user clicks a payment link, their browser or banking application recognizes the file type immediately. For more details on this configuration, check 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.
