$File::Find::dir is the containing directory of the path item (= the dirname in
http://perldoc.perl.org/File/Basename.html ). Finally, note that File::Find has
some severe philosophical limitations, and you should look into alternatives on
CPAN such as https://metacpan.org/pod/File::Find::Object (which I happen to
maintain) or https://metacpan.org/pod/Path::Iterator::Rule#SEE-ALSO . For more
about that, see:
