Downloading iTunes music to flash drive
Can you Download iTunes music to a flash drive, from one iPhone 14, to play on another iPhone 13
iPhone 13 Pro Max, iOS 16
No. You cannot extract music from an iPhone's Music App onto a flash drive.
You can copy music from a computer to a flash drive, and access it on an iPhone and play it through the Files App or a third party app such as VLC, but not through the iPhone's Apple music app.
