Also "." was extremely common, used on large DEC systems (RSX, VMS) and Tandem/NonStop as home systems like RISC OS. Multics and VOS use '>' as the separator (and '<' to indicate the parent). The Multics-style paths really are the cleanest, in my opinion. Edit: We run the Public Access Multics system at https://ban.ai/ https://ban.ai/
