ⓘ Rich Text Format Directory

Rich Text Format Directory, also known as RTFD, or Rich Text Format with Attachments, is a primary document format of TextEdit, an application native to NeXTSTEP and OS X which has also been ported to other versions of Unix. The file format is based on the Rich Text Format, but can also include "attachments" such as images and animations.

In three dozen of documents is a package, a folder that contains files. It contains a rich text file format txt.rtf, which contains commands for formatting text and commands, including images or other attachments contained in the package. The images used in the document are stored in the package in their own formats.

One big advantage with three tens is that it supports high quality scalable graphics formats, such as PDF, so that the rtfd file can print without loss of information on large paper sizes. The standard RTF format also supports a number of scalable image meta file formats.
