How to transfer files from one sd card to another?

A

AC Question

Is there a simple and easy way to transfer all my files from my old sd card to a new one?
Basically, I purchased a 16gb sd card for my LG G Stylo since the one I have is too small for me now, 4gb. My device isn't rooted. It's on MetroPCS network, if that even matters.
Also, does the new sd card need to be formatted for my device and if so, how would I go about doing so? I didn't see an option in my settings for formatting an sd card.
Any help is much appreciated!!
