well... you have to deal with the top level dir as well:

   Dir['./**/*.txt'] + Dir['*.txt']

that's always bugged me about "**".

You can also use find for more flexibility:

   require 'find'

   txt = []

   Find.find(".") do |path|
     Find.prune if File.basename(path)[0] == ?.
     txt << path if path =~ /txt$/
   end
