You need to look for the share not the local folder. A shared folder does not necessarily have the same name as the local folder.
If it is a Network share you are trying to locate, then use Windows Explorer and look in Network (Places). If it is a Media Server share then use your Media Server software to locate the share.
The WDTV Live cannot tell you the file path to the folder because it does not know it. Your PC will only be advertising the PC name and the share name.
