What DOC and DOCX files are

DOC

DOC is the classic binary document format of Microsoft Word, the default until Word 2007 switched to DOCX. Word, LibreOffice and Google Docs still open it, but it cannot hold some newer Word features, and the same document saved as DOCX can be up to 75% smaller.

DOCX

DOCX is a Microsoft Word Open XML Document file format used for word processing documents. It is the default format for Microsoft Word 2007 and later versions, based on XML for improved efficiency and reliability.
