File Extension RTFD Description:

The Rich Text Format Directory, or the file extension RTFD, is the fundamental format for documents created through the TextEdit program. This application is a native of the NeXTSTEP and Mac OS X operating systems. However, the files with the .rtfd file extension are relatively present in other versions of UNIX.

The file extension .rtfd is originally based on the Rich Text Format with the RTF file extension. The main difference of files with the .rtfd file extension from those with the .rtf file extension is that the former can carry attachments. Such attachments can be in the form of images, commands to include the images, or other attachments that were previously contained within the bundle. The images that can be attached to files with the .rtfd file extension are stored in the bundle, using their native formats, i.e. JPEG, BMP, and PNG.

The RTF file extension is being used in the Windows operating system, while the file extension RTFD is in Mac OS X. The files with the .rtfd file extension are not portable to the Windows operating system; thus, they can only be opened through the use of the TextEdit program in the Mac OS X. The advantage of using the file extension RTFD is that it has the capability to support high quality and scalable image formats, i.e. PDF. Additionally, the RTFD file extension can be printed with no loss in the information of the images attached on larger sizes of paper.

The TextEdit program, which uses the RTFD file extension, is an open source word processor and text editor. It served the purpose of replacing the previous SimpleText program when Apple Inc. acquired it for the Mac OS X operating system. Aside from the use of the file extension .rtfd, the TextEdit application also utilizes the Rich Text Format and other plain text files.
