How to Upload a Save to Your Space Engineers Server

Last updated: September 18, 2026

A Space Engineers world is a folder of files. This guide shows you how to transfer an existing world from your PC to your server so the server loads it.

What a World Folder Contains

Each save is its own folder. The important files inside it are:

File Contents
Sandbox.sbcWorld settings, the mod list, GPS markers, and factions.
Sandbox_config.sbcSession rules: game mode, player limit, PCU and block limits, experimental mode.
SANDBOX_0_0_0_.sbsThe actual world data - grids, objects, and asteroids.

Step 1: Find Your Local Save

On your own PC, your saves are in:

%APPDATA%\SpaceEngineers\Saves\<YourSteamID64>\<WorldName>\

Step 2: Stop the Server

In the NolimitHost Game Panel, select your Space Engineers server and stop it from the Console page. A running server autosaves and can corrupt your upload.

Step 3: Upload the World

  1. In the left sidebar, click Files and open the server's Saves/ directory.
  2. Upload your world folder, or the contents of it, into Saves/.
  3. Point the server at your world. In SpaceEngineers-Dedicated.cfg, set: 
    <WorldName>YourWorldName</WorldName>
<LoadWorld>/path/to/Saves/YourWorldName</LoadWorld>
    Make sure WorldName matches the folder name exactly, and LoadWorld points to that same folder.
  4. Save the config and start the server.
Note: Some panels expect the uploaded folder to be named World rather than after the world. Check your panel's guidance, or simply make the folder name and the WorldName / LoadWorld values match.

Step 4: Confirm It Loaded

Watch the Console page as the server starts. A successful load shows the world being loaded, followed by a "game ready" style message.

Important: Do not leave your own backup files inside the world folder. Space Engineers deletes anything it does not recognise the next time it saves. If LoadWorld points to a folder that does not exist, the server either fails to load or generates a brand-new random world.

Troubleshooting

Problem Fix
A random world loads instead of yoursLoadWorld does not match the uploaded folder. Fix the path so it points at the folder inside Saves/.
Settings look wrong after uploadingYour world's own Sandbox_config.sbc overrides the dedicated config. Edit it directly. See Configure Your Server.
Mods are missingEnable Experimental Mode so the world's mod list can load.
