How do I change the incoming mail sound? What do I use to copy the sound to the proper folder?  What is true proper folder?  John

App settings -> message notifications -> sound

The "sound picker" is standard Android and the available sounds vary by device make / model / Android version.

If you'd like to use your own custom sound - you'll need to copy them "somewhere" (such as into the Alarms directory) and use "something" (such as a file manager) to choose them.
