DOCX and RTF explained
DOCX is a ZIP archive containing XML that describes a Word document's content and formatting. Renaming one to .zip and opening it shows the structure directly.
RTF is a plain-text markup format for styled documents. Opening one in a text editor shows readable markup, which makes it unusually durable — but it supports only basic formatting.
- Where DOCX files come from
- Microsoft Word, Google Docs exports and Pages exports.
- Where RTF is used
- Cross-application document exchange, especially from older software.
