What is the circumstance under which you are trying to perform a 
NotebookOpen[] operation?

If you are working with a collection of notebooks which 
reside within a specific portion of the directory tree, 
then you may not need to monkey around with NotebookPath
at all.  Instead, store the path to the top level directory 
as a string and then compute the value of the absolute path
at execution time by concatenating this top directory
string with a relative path.  NotebookOpen[] does accept
absolute paths.
