I have not used itunes in a few years but what I used to do was go to the itunes folder on the computer and copied from there.
Recently, I purchased SanDisk iXpand 32GB pendrive with the hope of relieving space on my 16GB 6S Plus phone. Though I could transfer photos and contract and other sundry items, iTunes music could not be transferred. To my query, SanDisk replied that it is the limitation imposed by iPhone, where music is "sandboxed". I want to know is there any trick by which I can transfer music to pendrive and play from there? Thank you for reading the post.
