Could you briefly describe what a strongly typed file system is,
sorry?

Is this analogous to a "strongly typed" programming language?  Is in
this sense C a strongly typed language?  One must declare the type and
can interchange--with some exceptions--only same types.  Would Lisp be
a weakly typed language, because the type information is stored in the
data itself?

I really like Emacs but I think vi(m) is not so bad, after all.

For what it's worth, both of you can go on indefinitely, I like to
read about these things 8-)
