Introduction The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation for cross-platform document interchange with Microsoft products. Most word processors are able to read and write some versions of RTF. The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc.
Technical details Unlike many word processing formats, RTF code can be human-readable: when an RTF file is viewed as a plain text file, the contained ASCII text is legible. The formatting code is not too distracting nor counter-intuitive, provided that the document's creator kept formatting concise. Office Open XML documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files, along with a specification of the relationships between them. Depending on the type of the document, the packages have different internal directory structures and names.
Associated programs WordPad, LibreOffice, Microsoft Word. Microsoft Office, LibreOffice, Kingsoft Office, Google Docs.
