transfer the custom ringtones I have custom ringtones on my iPhone5s which show in Tones on iTunes. They were originally setup years ago on older iTunes.

I am trying to setup an older iPhone5c and would like to transfer the custom ringtones, but can't seem to find how.
I found the original on my Mac.

There seemed to be no means of selecting in iTunes, so I tried (shudder) dragging the file to iTunes which worked.
