Yet more information regarding Macintosh files is stored by the Finder in a hidden file, called the "Desktop Database". Because of the complications in storing different parts of a Macintosh file in non-Macintosh file systems that only handle consecutive data in one part, it is common to only send the Data fork or to convert the Macintosh file into some other format before transferring it.
