Different Rob(ert), but yes, there is a [] method defined on Dir

There's no reason to think that it wouldn't work on your Windows  
system.  Mine is a Mac, but the ruby code is the same:

irb> RUBY_VERSION
=> "1.8.6"
irb> Dir['*.rb']
=> ["listdiff.rb"]
irb> Dir['code/ruby/mailing_list/**/*.rb']
=> ["code/ruby/mailing_list/assoc.rb", "code/ruby/mailing_list/ 
merge_csv.rb", "code/ruby/mailing_list/sales_data_graph.rb", "code/ 
ruby/mailing_list/simulating_vehicles.rb", "code/ruby/mailing_list/ 
sorting_with_numbers.rb"]

Note that *I* have a code/ruby/mailing_list/ directory, but you'd have  
to use directory names that exist on your system.
