Upload World Project Zomboid Server


When playing on a Project Zomboid server, the desire to continue from a singleplayer save can be strong. Luckily, Project Zomboid servers allow you to upload a singleplayer world in order to transfer all of the world data to a dedicated host for use. This is beneficial to keep your base and exploration, rather than start from scratch with a brand new world. Uploading a Project Zomboid world to a server can be confusing for unfamiliar players, so we have created this Apex Hosting guide to ease you through the setup process.


  1. On your computer, navigate to the following location:
    Windows – C:\Users\[YourUser]\Zomboid\
    MacOS/Linux – ~/Zomboid/

  3. Locate and enter the Saves folder, followed by the Survivor folder.
  4. Find the desired world folder that you wish to upload.
  5. (Optional) Using a program like 7-Zip, create a zip folder of your world.
  6. Using FTP, upload the world into the /Saves/Multiplayer/ folder.


Confirming the Upload

  1. Navigate to the Apex Server Panel and stop the server.
  2. Proceed to the FTP File Access on the left-hand side.
  3. Enter the Saves folder, followed by the Multiplayer folder.
  4. If zipped, select your world file, then press Unzip in the top-right.
  5. Once the world is unzipped and looks correct, you can proceed to load it.


Loading the World

  1. Navigate to the Apex Server Panel.
  2. Scroll down and press the Change World button.
    World Name
  3. Enter the world name to match the save folder you uploaded.
    World Name
  4. Restart the server to load up the world.

With that, your Project Zomboid world should now be uploaded to the server for use!

Common Issues

A new world was generated:
Oftentimes, this occurs when there are issues within the loading process. First, visit the /Saves/Multiplayer/ folder in the FTP File Access and ensure that your world folder is there. If only the .zip file is present, ensure you unzip it before proceeding. Afterwards, return to the main panel page and press the Change World button. Here, ensure that the set name matches your uploaded folder exactly. Once this is done, restart the server once more.

Some of the world is present, but some is missing:
This often occurs when there is an issue during the upload process. Since all of the map data is stored within the world folder, the world can become problematic if some files do not properly upload. As this often occurs when uploading a folder instead of a zipped file, we recommend using a program such as 7-Zip to zip the whole world folder before uploading. This should prevent any files from failing to upload.
