🎯 Tips & Tricks
Make sure FOSE is installed and you launch the game through fose_loader.exe, not the default launcher.
After installing, load a save and save again to see the size reduction—it's most noticeable on older saves.
If you use a mod manager, let it handle the FOSE installation to avoid conflicts.
