files that hold the settings

This is probably answered before but I was unable to find it.
Which setup files would I need to copy to a new SD card it i wanted to burn a new SD and just put in the files from an old but working SD card on a raspberrypi.
Wasn't quite sure how to write this but I think you get the idea.

Thank you Rich Prim
