what does rt&f mean
The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft products.Most word processors are able to read and write some versions of RTF. Braces ({ and }) define a group; groups can be nested. 2  A backslash (\) starts an RTF control code. 3  A valid RTF document is a group that starts with the \rtf control code. 4  In the example above, the \b control code invokes boldface type; the example uses a group to limit the scope of the boldface control code.
