MacOS's current Finder dates from 2001. Earlier versions of "Finder" were a completely different piece of software - different code, different interface, different UI metaphor. File manager software predating it:
Windows Explorer
GNOME/Nautilus
KDE/Konqueror
X11/xfm (X File Manager)
sundry proprietary Unix workstations
All of the above interfaces share the same interface lineage as Mac OS, lying as they all do downstream of Xerox PARC. And all have converged on the same interface principles - visible path, a button to ascend to the parent directory, etc.Everyone who comes to Finder from anywhere else complains. Finder is weird for the sake of being weird.
