How it works.
1
Upload your .sav file
Drop or browse for your Satisfactory save from %LOCALAPPDATA%/FactoryGame/Saved/SaveGames/
2
View and edit
The header is parsed and displayed. Edit the session name freely.
3
Download modified save
The edited header is combined with your original compressed game data and downloaded.
Before you edit
Always keep a backup copy of your save. This editor only modifies the save file header. Deep edits (inventory, buildings, research) require a more advanced tool.
