Frequently asked questions
How do I back up Foundation?
Copy the Save Game folder with the game closed. Config sits beside saves in documents. Cloud copies in userdata and GOG storage mirror it. Restoring means putting the documents tree back.
X4 Foundations too?
This covers the Polymorph city builder only. Egosoft X4 Foundations documents separately. Never mix their trees.
