I'm trying to settle a debate between me and some colleagues about two-panel file managers in MS-DOS/PC DOS.
According to my own recollection the first was DV.EXE (see EDIT below), but some of my colleagues are adamant that NC.EXE (Norton Commander) was the first.
Could be we are all wrong and there was another that preceded those.
Please note: We are looking for a proper DOS program. Not a CP/M program that could also work under DOS.
EDIT: I was able find the original license and box of DV in our company archive.
"DV The DualView FileManager" (c) 1984 by Osmond Software Works Ltd.
The license was dated October 27 1984.
I tried finding out more about Osmond Software Works, but I'm drawing a blank there.
