|DOC is a filename extension for word processing documents, most commonly in the proprietary Microsoft Word Binary File Format. Microsoft Word 2007 and later, the binary file format was replaced as the default format by the Office Open XML format, though Microsoft Word can still produce DOC files.
|The Office Open XML file formats are file formats that can be used to represent electronic office documents. For example, there are formats for word processing documents, spreadsheets, and presentations and specific formats for material such as mathematical formulae, graphics, bibliographies, etc.
|🔸 Technical details
|Binary DOC files often contain more text formatting information (as well as scripts and undo information) than some other document file formats like Rich Text Format and HyperText Markup Language but are usually less widely compatible.
|Office Open XML documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files, along with a specification of the relationships between them. Depending on the type of document, the packages have different internal directory structures and names.
