- The Sound Designer II audio file stored with the .sd2f extension, which comes from the format's classic Mac OSType "Sd2f" and appears instead of .sd2 on files that have passed through Mac software. The format is the same Digidesign/Pro Tools big-endian PCM audio as .sd2.
- OPML (Outline Processor Markup Language) is an XML-based format used to exchange outline-structured information. It is most commonly used to share lists of web feed subscriptions (such as RSS or Atom feeds) between feed readers and aggregators.
