Wrath campaign saves can depend on game version, DLC, and mods. Preserve the entire Saved Games folder plus the working mod list, and keep it separate from Kingmaker.
For this PC reference, the documented storage is Windows: %USERPROFILE%AppDataLocalLowOwlcat GamesPathfinder Wrath Of The RighteousSaved Games. The known file or folder pattern is *.zks packaged saves. Wrath uses Owlcat .zks packaged saves in a title-specific LocalLow directory. Sharing the extension with Kingmaker does not make the internal content interchangeable.
Backup guidance: Close Pathfinder: Wrath of the Righteous, let the launcher finish any synchronization, then copy the complete documented save directory to a dated folder outside the live path. Preserve companion files rather than selecting only the newest-looking record. Storefront cloud can synchronize the same campaign files; make an offline directory copy before mods, DLC changes, or migration. Launcher and cloud context matters because The active Steam, GOG, Epic Games Store installation determines which local profile and cloud copy can overwrite the save. Identify the storefront and account before restoring files.
Compatibility and recovery should stay conservative. Treat saves as version-, storefront-, account-, and mod-sensitive unless the game or a separately verified migration workflow proves otherwise. A similar filename or extension is not evidence that two releases are interchangeable. If the expected progress is not visible, If progress is missing after a restore, confirm the active Windows account, storefront/profile, cloud state, and exact directory first. Restore the untouched backup before experimenting with individual files or older autosaves.
