     Probably. Unfortunately, I can't test its behavior right now.

     Not so simple. Those label is part of "Program Files" LFN, as far as I

     I doubt that there was/is label from boot sector. If you wish, I may
trace/ask what does VC for accessing label, but I doubt that it uses
something other than searching vlabel.
