I'm guessing that the reason why File.directory?(d) == false was
File.exist?(d) == false.

File.join is intended to absorb the deference of path separator among
platforms.  File.join(a,b,c,d) is equivalent to

  [a,b,c,d].join(File::SEPARATOR)

So, File.join('c:/', 'windows') should be File.join('c:', 'windows').

I'm afraid documentation about 1.7 is written in only Japanese.  That
is being written on an Wiki system.
