What is a .doc file?

The .doc file extension historically represented documents created with Microsoft Word, a proprietary word processing application. These files are rich text documents that can contain formatted text, images, tables, and other objects. While widely used in the past, newer versions of Word have largely transitioned to the .docx format.
