It has been my experience that use of opendir/closediror File::Findand its ilk does not generally elude a Seeker who quotes the use of a CPAN module in their question.

I do find, however, that use of -Xfrom perlfuncdoes often elude folks who do not use Perl on a regular basis.

I provided an example of that built-in functionality which most closely matched what I felt Jeri was seeking.

I would also note that my then-untested code worked without modification once tested.
