I have some pretty impressive game stats in KPatience, especially in Freecell where I'm 251-0. I'm about to upgrade my Kubuntu and I don't want to lose those stats. They must be in a file somewhere but it beats be where.
Anyone know?

In KDE 5, the file is ~/.config/kpatrc
I'm not completely sure what the file was under KDE 4, but likely either ~/.kde/share/config/kpatrc (or similar name) or ~/.kde/share/apps/kpat (or similar name).
