What is a .RTFD file?
RTFD is the macOS rich-text format that bundles images and attachments. Created by Apple.
- Did you know
- RTFD is really a folder, letting a TextEdit document carry its own images.
- RTFD began on NeXTSTEP in the late 1980s as Rich Text with Attachments, extending RTF so a document could embed images and other files.
- Inside the bundle a file named TXT.rtf holds the formatting while attachments sit beside it in their native formats.
- What Analyser reads
- Open documents, ebooks and publishing files beyond Office: comic books (CBZ/CBT with ComicInfo + first-page preview; CBR/CB7 identified), Microsoft XPS, FictionBook FB3, iBooks, Scrivener, Visio VSDX, R Markdown/Quarto, RTFD, WARC/MAFF web archives, TeX DVI, legacy Hangul HWP, and WordPerfect/QuarkXPress/PageMaker identification.
- Depth of analysis
- .RTFD is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .RTFD file
- Drag a .RTFD file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
