What is .XFD file extension?
File that uses the Extensible Forms Description Language (XFDL) standard to represent a structured, legally-binding business form; contains business form data including layout, digital signatures, inline expressions, and business transaction details; addresses business transaction needs for auditability, non-repudiation, preservation of context, and security.
XFD files are the same as .XFDL files. They were designed to create standardized business forms and are used in government and business transactions.
NOTE: The United States Airforce discontinued the use of IBM PureEdge Viewer. You should use the Lotus Forms Viewer instead.
