Hello!

I like it, but it's not going to work. File.stat needs the the directory to 
exist. First you have to test that:

begin
   print "Dir = "
   mydir = gets.chomp
   dir = Root + mydir
   raise "No such directory" if not File.exist?(dir) # added
   raise "It's not a directory" if not File.stat(dir).directory? # changed
rescue => err
   puts err
   retry
end
