Find the save
- Windows: %appdata%\Factorio\saves
- Linux: ~/.factorio/saves
- macOS: ~/Library/Application Support/factorio/saves
Upload it
- Save the game one last time and quit.
- On Flux, open the server's Saves tab and press Upload a save.
- Press Load beside it. The server saves the map it is running, then restarts into yours.
Tip:Match the server's Space Age setting to the save. A base-game save loads with Space Age on and is migrated to the expansion; a save that used the expansion loads with it off only by losing everything the expansion added, because Factorio drops what belongs to a mod it no longer loads.
Mods
A save made with mods needs the same mods on the server. Add them in the Mods tab before you load it; the mods guide has the details.
Frequently asked questions
Which save does the server load?
The newest one in its saves folder, by the time it was written; the Saves tab marks it. After a restart it carries on from the newest autosave of that map. Load in the Saves tab switches to any other save.
Can I go back to single-player?
Yes. Download the newest save from the Saves tab and load it in your own game.
