Where does Android 7 store the ringtones?

[AC Question]

I wish to browse the ringtone stored folder

The system ringtones are not in a directory that is accessible via a file manager unless your device is rooted. User ringtones are on your internal storage.

My LG phone lets the user's ringtones be on the internal storage and SD card.
However, the built-in ringtones are hidden away in a system level folder.
