+ There are also UNC names of the form \\share\fullpath and
+ MSW unique volume names of the form \\?\Volume{GUID}\fullpath.
+
+ The latter provide a uniform way to access a volume regardless of
+ its current mount point, i.e. you can change a volume's mount
+ point from D: to E:, or even remove it, and still be able to
+ access it through its unique volume name. More on the subject can
+ be found in MSDN's article "Naming a Volume" that is currently at
