What ho one and all,

I'm guessing the answer is obvious, but perhaps I'm mistaken!!!

Just taken delivery of a new smartphone; it comes with a USB-a / USB-c charging cable.

the on-screen instructions suggest the best way to transfer files from the old to new, is with a USB cable. But does everyone have a USB-c to USB-c cable? What can I do with a USB-a cable? There is no suggestion as to what one is supposed to do, just use a USB-c cable.

I do not have an adapter nor any way to connect both phones, so how can it be done? Can I connect both to the computer USB-a sockets?

Thanks and toodle pip
