Question about Apple Lightning on SD card reader

Goodbye Lukas

I have now experimented for you (and also a little for me :-)).

I created a WAV folder on the SD card, then copied several *.wav files into it and connected the whole thing to the iPhone.

If you then go to the "Files" folder on the Apple device (iPhone, iPad) and go to the top of the folder hierarchy,
you will see your memory card.

The rest is easy: tap the folder and stay on it, select Copy in the menu and place the folder in any cloud / storage location.

Does that answer your question?
