The thing about Orthodox File Managers when they first came about, that does not occur today, was the amount of time that had to be devoted to explaining that particular features would not work on OS/2, Unices, Linux-based operating systems, or Windows NT because only MS/PC/DR-DOS let programs do things like directly manipulate stuff in some other program's PSP or directly peek/poke video RAM or the keyboard buffer; or that filenames did not necessarily have "extensions"; or that there was more than 1 type of timestamp; or that links and symbolic links existed; or that different people can have different local times on a single machine; or that directories actually have sizes.
Today, the DOS Think is far less prevalent.
Midnight Commander's screenshots would have looked a little off to OFM users with DOS Think. Today, it's the original MS/PC/DR-DOS tools that will appear odd to novices. They did things like have a narrow 8.3 filename column, omit the dots, use graphics in the filename for system files, use glyphs that one could only obtain through poking C0-range codes into video RAM, change UI elements as one pressed and released the Alt key, and so forth.
