DOC vs DOCX
DOC
A DOC file is the older, legacy Microsoft Word format (Word 97-2003), stored as a proprietary binary format. Still shows up in old archives and email attachments, but Word itself has defaulted to DOCX since 2007.
Used in: Legacy Word documents · Old email attachments
DOCX
A DOCX file is the modern Microsoft Word format — an editable document with text, formatting, images, and tables. It's the default for writing, editing, and collaborating on documents today.
Used in: Word processing · Collaborative editing · Office documents
