How can I copy notification sounds off my Windows 8 Lumia 920?

[Windows Central Question]

I have several notification sounds that I can't seem to locate independently anymore, but they are on my old 920. I would like to move them over to my 950, but I can't seem to figure out how to do that. They don't show up in the ringtones directory when I plug it into my laptop. Anyone know how I can do this?

Thanks!

Don't waste the effort, they're in the OS ...
Search Nokia Lumia sounds online - I remember a SoundCloud site that hosted all the sounds from Lumia's.
