Project Zomboid: Uploading a Save
Transferring a world requires moving specific database files. Note that uploading a Single Player save to Multiplayer is possible but requires extra steps to convert the character.
1. The Folder
Server saves must go into /Saves/Multiplayer/. Do not put them in `Survivor` or `Sandbox` folders.
2. The Name
By default, servers look for a folder named `servertest`. If your folder is named `MyWorld`, you must either rename it or edit the server config.
3. The Files
A valid save contains `map_p.bin`, `map_t.bin`, `chunkdata`, `zpop`, and `players.db`. You need ALL of them.
Step-by-Step FTP Upload
- Stop the Server. Uploading files while the database is locked will cause corruption.
- Connect via FileZilla using your credentials found in the Panel.
- Navigate on the remote server to:
/.cache/Server/Saves/Multiplayer/(or/Zomboid/Saves/Multiplayer/depending on installation). - Drag your local save folder (e.g., `MySave`) into this directory.
- Wait for all files to transfer. There may be thousands of small "chunk" files. **Do not interrupt it.**
Activating the Save
Now you must tell the server to load `MySave` instead of `servertest`.
- Go to **Startup Parameters** / **Server Settings**.
- Find the **"Save Name"** or **"Internal Save Name"** field.
- Change it from `servertest` to `MySave`.
- Start the server.
Common Error: If you load in and the map is reset but your character is there, it means the `map_*.bin` files failed to upload. If the map is there but zombies are reset, the `zpop` folder failed.
