Question: how to add ringtones to iphone windows 10?
Answer: Click the “Tones” section under On My Device in the left sidebar. Drag and drop the .m4r ringtone file from its folder to the Tones section in iTunes. Update: If drag and drop doesn't work, use copy and paste instead. Select the ringtone file in File Explorer and press Ctrl+C, or right-click it and select copy.
