You could use String.Split to break it into teh components:
string inp = "C:\TEMP\FDB2\27JUN2012.TEL136430D\NDDF PLUS DB\NDDF Plus DB"
string parts = inp.Split('\\');
Then it depends on how your paths will be organised: if it is always the third part you want, then
Will give it to you. Otherwise, you will have to look at each part and see f it matches whatever your criteria are. Without knowing more about the criteria, I can't say!
