g-file n.
[Commodore BBS culture] Any file that is written with the intention of being read by a human rather than a machine, such as the Jargon File, documentation, humor files, hacker lore, and technical materials.
This term survives from the nearly forgotten Commodore 64 underground and BBS community. In the early 80s, C-Net had emerged as the most popular C64 BBS software for systems which encouraged messaging (as opposed to file transfer). There were three main options for files: Program files (p-files), which served the same function as `doors' in today's systems, UD files (the user upload/download section), and g-files. Anything that was meant to be read was included in g-files.
