How to Load a Space Engineers World Save to GTX Gaming (Step-by-Step Guide)

If you’re running a Space Engineers server through GTX Gaming and want to upload your own world save—whether it’s a single-player world, a local scenario, or a previously hosted server save—the process is straightforward once you know where the files go. This guide walks you step-by-step through uploading a custom world to your GTX Gaming server so you can pick up right where you left off.

1. Prepare Your World Save Files

Before uploading anything, you need the correct world save from your computer.

Locating Your Saved Worlds

On your PC, Space Engineers stores worlds here:

C:\Users\<YourName>\AppData\Roaming\SpaceEngineers\Saves

Inside the Saves folder, you will see subfolders for each world. Every world contains several files (Sandbox.sbc, Sandbox_config.sbc, Storage, etc.). Do not rename these files, but you can rename the world folder so it’s easier to recognize later.

Zip the World Folder

GTX Gaming requires uploads in zip format.

1. Right-click your world folder.
2. Select Send to → Compressed (zipped) folder.
3. Save the ZIP file somewhere easy to find.

2. Log In to Your GTX Gaming Control Panel

1. Go to your GTX Gaming Control Panel.
2. Select your Space Engineers server from the list.

Once inside, you’ll see several tabs like Dashboard, Configuration Files, File Manager, and Backup Manager.

3. Stop Your Server

Before uploading any custom world, always stop the server to prevent corruption.

1. From the main dashboard, click Stop.
2. Wait until the server shows Stopped before continuing.

4. Upload Your World Save to the Server

Navigate to the Saves Folder

Inside the GTX File Manager:

1. Click File Manager.
2. Go to: /serverfiles/Saves/

This is where Space Engineers looks for world saves on GTX servers.

Upload Your ZIP File

1. Inside the Saves directory, click Upload.
2. Select your zipped world file.
3. After the upload completes, click the ZIP file and choose Extract.

You should now see your unzipped world folder inside the Saves directory.

5. Select Your Custom World in the Control Panel

Once your world folder is uploaded and extracted:

1. Go back to the Configuration Files tab.
2. Open SpaceEngineers-Dedicated.cfg (or the dedicated config editor).
3. Look for the Load World or World Name field.
4. Select your newly uploaded world from the dropdown menu.

If the world does not appear:

• Make sure the world folder extracted correctly
• Ensure the folder name has no extra special characters
• Refresh the configuration page

6. Start Your Server

With your world selected:

1. Return to the Dashboard.
2. Click Start.

Your server should now load your custom world save. The first startup may take longer depending on world size, mods, or voxel changes.

7. Common Issues and Fixes

World Not Showing in Dropdown:
Make sure the folder is inside /serverfiles/Saves/ and contains Sandbox.sbc.

Server Crashes on Startup:
Disable mods first—some local worlds use outdated or incompatible workshop mods.

Infinite Loading:
This usually means corrupted world files. Re-zip and re-upload the save.

Final Thoughts

Uploading your Space Engineers world save to GTX Gaming is simple once you know where the files belong and how the panel reads custom worlds. With the right folder structure and a clean ZIP upload, you can easily continue your adventures on a dedicated server with friends.
