I've always used something similar to the old Norton's Commander, since I used the DOS version on my old Atari PC. That included something called Servant Salamander (not free any more, see https://www.altap.cz/) and current the Donator's version of Free Commander (see http://freecommander.com/en/summary/).I didn't know there were still versions of NC out and about. This one (not free either, you get a trial version) looks prettier than Midnight Commander, which is free and has cross-platform versions (see https://midnight-commander.org/) but for me, like the original NC, looks very garish!

Linux file managers like Dolphin (see https://www.kde.org/applications/system/dolphin/) are clearly inspired by NC, when pressing F3 toggles the number of panels you have. All the same Dolphin looks kind vague when compared to equivalent managers.
