Unix has a concept of "current working directory". Windows has an
identical concept. But did you know that Windows keeps a working
directory FOR EVERY DRIVE?
C:\> CD Foo
C:\Foo> D:
D:\> CD Bar
D:\Bar> E:
E:\> C:
C:\Foo> D:
D:\Bar> E:
E:\> DIR C:
--lists everything in C:\Bar--
E:\> DIR C:\
--lists everything in C:\--
How random is that?
