RTF
The Rich Text Format (RTF) is one of the document formats supported by Microsoft Word and many other Word processing applications. RTF is human readable file format invented for interchanging formatted text between applications. It is an optional format for Word that retains most formatting and all content of the original document.
Most of the Word processors (including Microsoft Word) uses the XML-based file formats, Microsoft has discontinued enhancements to the RTF and still supporting it. The last version was 1.9.1 released in 2008.
