A file extension for word processing documents; most commonly for Microsoft Word.
"doc" (an abbreviation of 'document') is a file extension for word processing documents; most commonly for Microsoft Word. Historically, the extension was used for documentation in plain-text format, particularly of programs or computer hardware, on a wide range of operating systems.
This document format has been superseded by the "docx" format as of Microsoft Word 2007 going forward.
