ls of My Documents

cygwin is a unix operating system emulator that runs on top of windows.
the pathame / in cygwin is actually
the windows pathname c:\Cygwin cygwin
has a symbolic link to disks on the system underneath the directory /cygdrive to get to the
disk path c:\dirname assuming "dirname" is a directory named by windows, the cygwin path would be /cygdrive/c/dirname

here we see the listing of "My Documents" and the fact that "My Pictures" is a subdirectory of "My Documents."
