[Rails] Re: clue about deleting empty directories in a file structure ?

[SOLVED]  found a better module extending FileUtils .. it works

module MyExtensions

  module FileUtils

    # Gracefully delete dirs that are empty (or contain empty children).

    def rmdir_empty(*dirs)

      dirs.each do |dir|

        begin

          ndel = Dir.glob("#{dir}/**/", File::FNM_DOTMATCH).count do |d|

            begin; Dir.rmdir d; rescue SystemCallError; end

          end

        end while ndel > 0

      end

    end

  end

  module ::FileUtils

    extend FileUtils

  end

end

I have been playing around w Dir and FileUtils, and I can delete the stuff I want to get rid off , but then I get some empty folders 

is there any way to remove ( recursively.. ) all empty folders ?

I found a piece of code dated 2007 ... is there anything new around ?

thanks for feedback
