&quot;Originally conceived and implemented by programmer Bruce Horn, the resource fork was used for three purposes with Macintosh file system. First, it was used to store all graphical data on disk until it was needed, then retrieved, drawn on the screen, and thrown away. This software variant of virtual memory helped Apple to reduce the memory requirements of the Apple Lisa from 1 MB to 128 KB in the Macintosh. Second, because all the pictures and text were stored separately in a resource fork, it could be used to allow a non-programmer to translate an application for a foreign market, a process called internationalization and localization. And finally, it could be used to distribute nearly all of the components of an application in a single file, reducing clutter and simplifying application installation and removal.&quot;<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Resource_fork" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Resource_fork</a>
