What is MIME type "application/vnd.arastra.swi"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
application/vnd.arastra.swi is a vendor-specific MIME type. It tells software that the file uses a proprietary format developed by Arastra.
Files with the SWI extension use this MIME type. They usually contain configuration data, operational instructions, or specialized commands needed by Arastra’s applications.
- Vendor-specific use: Designed solely for Arastra’s software systems.
- Proprietary format: Contains data that is processed only by dedicated applications.
- System communication: Helps systems know how to interpret and handle the file.
If you need to work with these files, use the proprietary software from Arastra. For more technical details and the official registration, check the IANA entry.

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 are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
