I also own a TyTN and was wondering how to set an mp3 for ringing without
putting it in the \windows\rings folder, I prefer let it on my SD Card...Did
already manage to do that ?
I don't really use mp3 ringtones, preferring old-fashioned phone-ringing sounds (although I do use different "ring" sounds for different people). But with some testing, it looks like there's an easy way to set the ringtone without having to copy it yourself to \windows\rings, but the result is the same -- the system just copies it for you.
The shortcut to doing this is to go to your MP3 file in File Explorer and click&hold on the file. When the menu pops up, one option will be to set as ringtone. But it will then just copy it for you to the rings folder, and set it as your primary ringtone. It will then also be in the pulldown menu in contacts.
But again, it looks to me like there's no way to set a ringtone that's not in the rings folder, if your goal is to save memory. It does seem likely that there's a way to change the rings folder in the system registry, but then you'd ONLY be able to use ringtones in the memory card folder, so you're buying yourself a headache. But I haven't gotten into registry changes yet.
