Pat Farrell mentioned Nikolai Bezroukov's "A Second Look at the Cathedral and Bazaar" text via which I found another very interesting text: The Orthodox File Manager (OFM) Paradigm. Dr. Bezroukov said,
"Although originated in the USA, the OFMs became mostly a European phenomenon with a very strong following in Eastern Europe (especially in former USSR countries), Scandinavian countries and Germany."
It's true that once learned them in a former USSR country I was never able to depart with them and until now have very vague idea of Windows's native interface, because I always have one of these wonderful pieces of software installed. I don't know how one can live without them.
In case you wonder what "Orthodox File Managers" are (I never heard this term before) examples include Norton Commander, Total Commander, Midnight Commander, Northern Captain etc.
Ernie's answer jumped into my brain when I saw the title, he just beat me to it, and was probably better phrased.
I had not heard the phrase before this thread, and haven't used any of such file managers.
I generally change computer too often to get very interested in customizing them. About all I do is install cygwin on all windows boxes so I can type ls and grep.
I've become a shell guy, as the gui stuff changes too often.
I think a lot of the customization is really closer to religion, be it orthodox, reform or conservative, or even Catholic versus Calvanist. I can't even figure out why Linux folks argue over KDE vs Gnome.
