Mapping Drive

Do you have to map each shared folder when mapping the drive? I can not seem to map documents,pictures, videos on  public shared folders in the same drive  IE  (Z) drive. In other words, do I have to have to  map a drive for each shared folder?  I just wanted to map the drive to show all shared folders. My pc does not give me the option to do so. Maybe I am doing something wrong. I go to network-map drive, assign a drive letter IE (Z) and then I have to pick one of the 4 folders to map. Please advise.

You seem to have a network hard drive, which one do you have? To Map it you can use the WDlink app, check the link below.
