There are a few reasons you might need to know your save location for Satisfactory. Save Editors already exist, allowing you to edit the .sav files the game provides. As well as save files, you will find your configuration files too, which you can change on the fly without having to actually enter the game. You can also delete saves, back them up and transfer them to others.
At the time of writing this guide, Satisfactory was in its early access. For that reason, there may be a few things different in this guide compared to your own game depending on future updates. If you’re interested, we’ve covered many more Satisfactory Guides here at PwrDown!
Save Location
The default save location for Satisfactory is currently inside of your AppData > Local folder. Specifically, you should head to the following directory:
C:\Users\YOUR USER\AppData\Local\FactoryGame\Saved
AppData is usually a hidden folder and inaccessible. You can show the folder by heading to the C:\Users\YOUR USER\ directory and checking the ‘Hidden Items’ option under the view tab.

Alternatively, you can open your Start Menu and input %AppData% into the search bar and hit enter. Doing so will take you straight to the AppData folder where you can find your Satisfactory save files.
The previous location for Satisfactory saves was in Documents > My Games > FactoryGame. Although it was changed to the AppData folder in an update. The game is presumably also saved to the cloud.
