Thanks!  Now I know how to list a drive, since Dir.new.("/cygdrive/w")
worked. I never ran into this in pickaxe.

Why didn't it just use /c instead of /cygdrive/c ?  I've seen this kludge
used several times and it almost make sense (at least as much sense as
windows does overall <grin>).

This just falls in the nuisance category, since one can start at the root
and map out a drive in a portable way.

cygwin is a compatibility layer that allows the unix-ish stuff of Ruby to
run on Windows. So cygwin 'unix-izes' your drives by prefixing them with
/cygdrive/, then the drive letter without a colon.

Your second example, of course, actually runs cmd.exe, so of course you get
a native result.

There are other ways to currently do Ruby on Windows
(http://www.rubycentral.com/book/win32.html) and there have also been recent
discussions for more native Windows support
(http://www.rubygarden.org/ruby?FutureWindows).

This bit you've hit upon is a bit awkward unfortunately, but I've been using
Ruby on Windows only for some time now and it works great.
