Detailed Description

AppleSingle & AppleDouble.

Permits storing certain metadata alongside the byte stream of a file, used for several Apple products

On classic Macintosh systems, each file has two associated parts called forks: the data fork and the resource fork. Classic 68000 applications store all the executable data in the resource fork, which is usually not transferred to non-Macintosh platforms. The AppleSingle and AppleDouble formats provide a way to store both the data and resource fork, or the resource fork, as a separate file, alongside other metadata, which is essential when storing it on a non-Macintosh system.

This container format was first invented for the A/UX Apple UNIX system. It has two versions, and version 2 is used most commonly. See also Apple::MacintoshResourceFileFormat.
