.rtfd File Extension

Developer: Apple
File type: Rich Text Format Directory File
You're here because you have a file that has a file extension ending in .rtfd. Files with the file extension .rtfd can only be launched by certain applications. It's possible that .rtfd files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .rtfd file?

RTFD files are text documents that provide support for attachments containing PDFs, other files and documents or images. These text documents in the RTFD extension essentially have the same support and features of RTF documents, but are commonly known as Rich Text Document Directory files. Initially, RTFD format technology was developed for NeXT OS versions, and today, Mac OS X provides more support for these RTFD files. In Mac OS X, users can open and view the content attached to these RTFD files by selecting "Show Package Contents" in the right-click menu, and these attachments are mostly other files added to an RTF document.

how to open a .rtfd file?

Launch a .rtfd file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .rtfd file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .rtfd files aren't yet associated with it. In this case, when you try to open a .rtfd file, you can tell Windows which application is the correct one for that file. From then on, opening a  .rtfd file will open the correct application.

Apple TextEdit

Apple TextEdit

Apple TextEdit is a text editor program and an open-source word processor too, which is first used in NeXTSTEP and OPENSTEP, but now integrated in most recent versions of Mac OS X. It is also considered a GNUstep application for other operating systems that are Unix based, like Linux computers. This program is operated by Advanced Typography by Apple so expect several advanced typography related features. The main function of this software is to read and write documents in plain text, HTML formats, Rich Text Format, and Rich Text Format Directory. It can also open Simple Text files but does not have the capability to save documents of that format. Mac OS X version 10.3 supports Microsoft Word documents, while Mac OS X version 10.4 can open and save Word documents in XML file. Mac OS X version 10.5 is able to read and write Office Open XML as well as OpenDocument Text. Features included on TextEdit are formatted text support, addition of graphics, animations and other multi-media contents, automatic adjustment of letter spacing, as well as reading and writing support of character encodings.

a word of warning

Be careful not to rename the extension on .rtfd files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .rtfd. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
