What is a doc file?
Doc file extension can be created and viewed by Microsoft Wordpad or by Preview on the OSX. In computing, 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. Binary doc files often contain more text formatting information (as well as scripts and undo information) than files using other document file formats like Rich Text Format (rtf) and HyperText Markup Language (html or htm), but are usually less widely compatible.
