Why my Photon Scripts must be in a subfolder?

Hey, I have this problem were my Photon scripts must be in subfolders. When I put them in Standard assets folder or Plugins folder it gives me this error which says that the type or namespace PhotonView does not exist. I even tried replacing the class name with : Photon.Monobehaviour but it keeps giving me this error that something does not exist. Well I need to access the scripts by other scripts but I cant do that while they are in a subfolder. Any Help?
