What does doc on Microsoft Word mean?

Answer 1

The .doc suffix at the end of Microsoft Word filenames is short for "document." The suffix on computer filenames indicates the file's encoding convention (file format) rather than actual file content, but some do give you some clue about the type of content. For example, some files created with Microsoft Word end in .dot, indicating the file is a "document template." Moreover, the .doc suffix use only applies to versions of Microsoft Word prior to Office 2007. Word 2007 document files end in .docx, template files end in .dotx, macro-enabled document files end in .docm, and macro-enabled document template files end in .dotm.
