About .asy Files
ASY files are text-based files used for creating technical graphics and schematic symbols.
They serve two primary purposes. One is for the Asymptote language, which lets you script precise vector graphics for technical diagrams. The other is for LTspice symbols, representing electrical components in circuit schematics.
- Asymptote Use: text/x-asymptote (and sometimes text/x-kotlin) files let users generate high-quality vector images. Tools like the Asymptote interpreter and LaTeX are used to process these files.
- LTspice Use: text/x-spreadsheet and text/plain MIME types indicate that these files serve as symbol descriptions in LTspice schematics. LTspice itself reads these files to display component symbols accurately.
According to FilExt.com, the .asy extension is versatile because it combines both graphical scripting and schematic symbol functions in a plain text format.
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.
