Upload savegame in Factorio

This guide explains how to upload a savegame to your Factorio server.

Important: Uploading the savegame can replace the current game state on your server. If you want to keep it as a backup, download the existing savegame to your computer first.

Preparing the savegame for upload

1. Open the folder containing your Factorio savegames: %appdata%\Factorio\saves The AppData folder is hidden by default in Windows.

2. Find the ZIP file of the savegame you want to upload.

3. Extract the ZIP file temporarily. The starting structure in our example looks like this:

   spaceageexp.zip
   └── spaceageexp
   

4. Rename the extracted folder spaceageexp to my-save.

5. Pack the my-save folder as a ZIP file again. When packing it, select the my-save folder itself, not only the files inside it.

6. Rename the new ZIP file to my-save.zip.

7. Check the finished file. It must have exactly this structure:

   my-save.zip
   └── my-save
       ├── locale
       ├── script.dat
       ├── level.dat
       ├── control.lua
       └── ... other savegame files
   

The ZIP file name and the name of the folder on the first level must be identical. The folder my-save must appear only once, and the savegame files must be directly inside it.

The ZIP file must not look like this:

my-save.zip
└── my-save
    └── my-save
        ├── locale
        ├── script.dat
        ├── level.dat
        └── ... other savegame files

An additional parent folder such as my-save/my-save prevents the savegame from loading.

Uploading the savegame

1. Stop your server via the web interface and wait until the status shows Server not running.
2. Connect to the Gameserver-FTP using your FTP program. You can find the login details in the FTP overview by clicking FTP.
3. Open the /saves folder in Gameserver-FTP. If the folder does not exist yet, create it.
4. Upload the file my-save.zip directly into the /saves folder.
5. Confirm replacing the existing file if your FTP program asks you to.
6. Start your server again via the web interface.

The uploaded savegame is loaded when the server starts. Make sure the file is located directly at /saves/my-save.zip and not in an additional subfolder.
