In computing, DOC or doc (an abbreviation of ‘document’) is a filename extension for word processing documents, most commonly in the Microsoft Word Binary File Format. Historically, the extension was used for documentation in plain text, particularly of programs or computer hardware on a wide range of operating systems. During the 1980s, WordPerfect used DOC as the extension of their proprietary format.
