Not true!! The string "D:" refers to "the current directory on drive
D:", while the string "D:\" refers to "the root directory on drive D:".
They are not, were not, and will not be the same!

Since many people don't believe me, assume that there is a directory
"foo" on drive D:, and the current drive is C:. Stuff after "#" is
comments:
  C>cd d:\		# current directory on D: is root
  C>dir D:		# list root dir on D:
  C>cd d:\foo		# current directory on D: is \foo
  C>dir D:		# list \foo directory on D:
  C:dir D:\		# list root directory on D:

I assume you understand and merely mistyped, but please don't confuse
the innocent on this. A drive name used without an *explicit* directory
refers to the current directory on that drive, which may very well not
be the root. This is useful when you do it on purpose...
