FDX (Final Draft Format)

Final Draft's file format — the industry's de-facto standard for exchanging screenplay files.

FDX is the file format of Final Draft, the long-standing industry-standard screenwriting application. When a production, agency, or contest asks for 'the Final Draft file', they mean an .fdx — element types and formatting travel with the document.

Most modern tools read and write it, which keeps your script portable between collaborators regardless of what anyone drafts in.
