Subject: Test equality of each element in an array

I want to see if any element of an array is equal to a file extension

Something like

require 'find'
require 'FileUtils'
src="/folder/on/drive/which/contains/other/folder/and/files"
dest ='another place'
extNot2move = %{jpg,JPG,pdf,PDF,MRW}
Find.find(src) do |fn|
  if File.file?(fn)
    if extNot2Move.{any of the elements} == File.extname(fn) ## this is
the test I'm interested in
      FileUtils.Move(src, dest)
  end
end

I think I could do it with a extNot2Move.each with a block following,
but it seems like their should something more concise.

Thanks from a Ruby newbie
