Which one is the folder for KDE settings

Hi,

on my NVME I’m using different partitions for the system /root and for /home. The settings of KDE should be in ~/.config. Now I have had several new installations and I always keep the /home partition. But always after a new installation, all settings I have made to KDE so far are overwritten, and I have to set them again.

So which folder has to be saved and written back after a new installation so that all of my made settings are back again.

Thank you
Jo
