These "directories" are also available on DOS systems - which ultimately were derived from Unix, IIRC, through things like the CP/M operating system - I think I heard that Kildahl reversed the slash from what Unix has.

CP/M had no "subdirectories" ... Microsoft changed the Unix "/" in a pathname to a "\" for MS-DOS and PC-DOS.


So many "stories" about Gary Kildahl - one article says he came up with the concept of a BIOS - he focused on microcomputers.

Yes, he did invent the BIOS concept.


If you go to a command prompt in windows and type "dir" you will likely see these at the top of the list there, as well.

PC-DOS and MS-DOS 1.0 had no subdirectories. If you are running DOS 2.0 and up, or any version of Windows, "." and ".." are present.
