About .xfdl Files
XFDL files are files based on the Extensible Forms Description Language. They use XML structure and are defined by the MIME type application/vnd.xfdl along with related types application/xml and the now-deprecated text/xml.
They are designed to hold interactive form data. They can include layouts, input fields, validations, and even digital signatures to secure responses. This format is widely used in government and business environments for electronic forms that require structured data collection and processing.
- XML-based Structure: The file content is based on XML, making it accessible via XML editors and tools.
- Interactive Forms: Supports dynamic form elements, field validations, and calculations.
- Security: Often includes mechanisms for digital signatures to ensure data integrity.
- Use Cases: Employed in electronic filings, tax forms, surveys, and other structured data applications.
XFDL files can be opened and edited using specialized form viewers, XML editors, or dedicated XFDL applications. According to FilExt.com, these tools help users interact with the complex data and functionalities embedded in XFDL files.
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.
