Uploading Save Game Files to Your Factorio Server
Find Your World Save
You'll need to locate your world save on your PC. The default save location for Factorio's Steam version on Windows PCs can be found at %appdata%\Factorio\saves. World saves are packaged in Zip files, which ends up being really convenient, because it saves us some steps that other games have us do in having to zip and then unzip their files.
Upload to the File Manager
Now you'll need to upload your world Zip file to your server. Navigate to the File Manager on the top of your game panel (or connect via sFTP), and select the worlds folder. If you don't have a worlds folder, likely you haven't started up your server at least once for it to generate all the necessary folders and files needed to run the game. You can manually create the worlds folder ahead of time if that is what you prefer.
Upload your world Zip file into the worlds folder.
Some operating systems don't like to have spaces in file names, so to save ourselves some headaches before moving on to the next step, we will need to rename this world save to replace the space in the name with an underscore
Change Loaded Save
Now it's time to tell the server to load the world we've just uploaded, rather than generating a new one. Navigate to the Startup tab at the top of the page. Scroll down to the "save name" box and change it to your gamesave name. Make sure it is exactly the same.
Start the Server
All that's left is to Start or Restart your server to load up your world and continue playing on it!
