Sample code is below. It will copy the target files and directory from one location to another. What's considered best practice for handling IO Exceptions while coping files across a network? I used printStackTrace() but feel like this is just a place holder for a better solution. Is logging the answer and should there be another step beyond logging to actually "handle" an error? Thank you for you feedback.
