      I wrote return if... and not next if ... for a reason.

      Since you are in a subroutine and not directly in a loop, next will jump to the next iteration of your caller's loop, and warns about Exiting subroutine via next at ... - don't you get such warnings? Since you don't know how File::Find works internally, that might cause very nasty behaviour.

      By the way I don't find that excessive use of newlines improves readability - on the contrary, you have to scroll more to see a relevant part of the code.

      Why are you using opendir/readdir to get the list of files in $DIR? Why not just pass $DIR to find and let that function find all of the files?

      I don't see how you're getting paths that include '/../'. I don't think that readdir will return them. Perhaps I'm missing some obscure symlink usage.

      I'm also surprised that you're not getting a 'Can't "next" outside a loop block' or 'Exiting subroutine via next' error as your next if line should surely be return if.

      If it's really necessary (and I don't think it is) then you could add another line that matches the problematic paths.

      return if m[/\.\./];
