If you want to store a backup of your save game, load it in local coop, or continue offline, you can use these steps to download your save file.
1. Open the File Manager
2. Navigate to /.local/share/7DaysToDie/
3. Right click the Saved
folder and click Download.
4. If you have a GeneratedWorlds
folder here, download this as well. If you used any Pregens or Navezgane, you will not need to download this.
5. If you plan on playing in Singleplayer or Coop, you can now place the Saves folder in C:\Users\username\AppData\Roaming\7DaysToDie\Saves
and the GeneratedWorlds folder in C:\Users\username\AppData\Roaming\7DaysToDie\GeneratedWorlds
.
