| Once you get used to two panes, it's hard to go back. From ~1990 to now (yikes, 30 years!), I've used these: - Amiga: Directory Opus (DOpus) - MSDOS: Norton Commander (NC) - Windows: Total Commander - Linux: Midnight Commander (mc) - MacOS: Tux commander Looking back at old Directory Opus screenshots tickles the nostalgic bone. I miss the colourcoded buttons. I wonder if Directory Opus was the first 2-split navigator, but probably not. |
In answer to your question of which was the first, the answer appears to be PathMinder (1984) and Norton Commander (1986). Both were for DOS so it seems to be an original innovation from the DOS world. Directory Opus first came out in 1990.
I wasn't familiar with PathMinder before looking at the wikipedia article but I was familiar with Norton Commander, as I think nearly everyone who used DOS in the late 80s would be. I personally favoured XTree (1985) more. Xtree didn't originally have the two pane view, but added it in 1989.
