Satisfactory worlds and saves

Your Satisfactory server can keep as many worlds as you like, each with its own saves. This guide shows where your saves are on your PC, how to bring a world to your server, how the Saves tab works, how to roll back to an earlier save, and how backups and the daily world reload look after your factory.

Where your saves are on your PC

The Steam and Epic versions of Satisfactory keep their saves in the same place. Press Windows key + R, paste %LOCALAPPDATA%\FactoryGame\Saved\SaveGames and press Enter. Inside is a folder named after your account:

Each save is one .sav file, named after its world (the game calls a world a session) and the kind of save, such as Our factory_autosave_1.sav. One file holds the whole world, so there is nothing to zip.

If your group played in a friend's game, the world is on their PC: ask whoever hosted to send you the newest .sav of that world.

Bring your world to your server

1. Pick the save. In the folder above, sort by Date modified and take the newest .sav of the world you want. A save made in co-op works too.

2. Start your server. The world goes in through the game itself, so the server must be running.

3. Upload it. Open the World Import tab and drop the .sav on it. It uploads straight to your server. Browser uploads stop at 100 MB: for a bigger save, upload it to the server root over SFTP, then press Rescan.

4. Load it. As soon as the upload finishes, the tab asks Load this world now? Press Back up and load. A save you put on the server over SFTP is listed under Potential saves on your server: pick it and press Import selected world first.

The import then:

1. backs up your server, as Before importing a world in the Backups tab
2. hands the save to the game, which loads it straight away (anyone playing is dropped while the world changes)
3. removes the upload once your world is running

A big factory takes a minute or two to load. Your world is now the one the server runs, and the one it comes back to after a restart. Nothing is overwritten: the world that was running before stays on the server with all its saves, and you can go back to it from the Saves tab.

A save that won't load

A save from a newer version of Satisfactory than your server's won't load. The import then says the game didn't load it, and the Before importing a world backup puts your server back as it was. It usually means one of two things:

• The save came from the Experimental branch. Set Game Branch to experimental in the Startup tab, restart the server and import again. Everyone who joins then needs the Experimental branch too.
• The game has just updated and your server hasn't yet. Restart the server: it checks Steam for a new build every time it starts. Then import again.

The Saves tab

The Saves tab, under Content in your dashboard's menu, lists every world on your server with its saves, newest first. The world the server is playing is marked Running now, and each save shows when it was made and how many hours of play it holds.

Load, Save now and New world go through the game, so they need the server running. Download works while it's stopped too.

Before Load or New world changes anything, the world that's running is saved, so you never lose the minutes since its last autosave and can always come back to it.

How saves are named

The list names each save by what made it:

Start a new world

1. Start the server, open the Saves tab and press New world.
2. Give the world a Name: up to 32 letters, numbers and spaces.
3. Pick a Starting area: Grass Fields, Rocky Desert, Northern Forest or Dune Desert.
4. Leave Tutorial on to play the opening tutorial, or switch it off to skip it.
5. Press Start it.

The world that was running is saved first and stays in the list. Everyone on is dropped and joins the new world, which is the one a restart comes back to.

Roll back to an earlier save

If something went wrong, such as a deleted build or a mistake you can't undo in the game, go back to a save from before it happened:

1. With the server running, open the Saves tab.
2. In your world's list, find a save made before the problem. Each one shows its time.
3. Press Load, then Load it.

The world as it was a moment ago is saved first as Saved before loading another world, so you can change your mind.

With the game's defaults, the autosaves only reach back about 15 minutes of play: three saves, five minutes apart. To go further back, look for a save marked (daily reload) or Saved before a stop, or restore a backup. To keep more autosaves, raise Rotating Autosaves in the Startup tab and restart the server.

Backups

The Backups tab keeps copies of your whole server that you can restore in one click. A Satisfactory backup holds every world and its saves, the server's own settings, its config files and any mods. The game itself is left out: it comes from Steam, so a backup stays small and quick, and a restore puts your worlds back on the game's current version.

Restoring a backup puts the whole server back as it was, every world included. To go back in one world only, load one of its saves in the Saves tab instead. How to create and restore backups covers the Backups tab step by step.

The daily world reload

Once a day, your server saves the world and loads it again. This is the game's own dedicated server at work, and it happens inside the running server: it isn't a restart, so the server stays online and your dashboard shows no stop. The save it makes is marked (daily reload) in the Saves tab.

It runs at midnight UTC unless you change it, which is 11 am in Sydney during daylight saving and 10 am the rest of the year. To move it to a time when nobody plays, change Daily world reload on the Server Settings tab, where the times are listed in your own time zone. Satisfactory server settings explains that tab.

Where saves live on the server

On the server, every save is in the Files tab, under .config/Epic/FactoryGame/Saved/SaveGames/server. Leave these files alone while the server is running, and use the Saves tab to load, save and download.

Each save holds a whole world, so old worlds add up. When you're sure you no longer need one, stop the server and delete that world's saves in the Files tab to free the space. A backup first is the safe way to do it.
