Where are the default Ringtones/Sounds?

[spyder560]

I imported some of my sounds from my Note 4 to use and now whenever I try to select a different alarm/ringtone, it doesn't give me a list of the default/factory alarms/ringtones. It defaults me to my folders.
How do I switch it back to pull up the default alarms/ringtones and be able to listen to them on the fly?
