Necesse World Settings and Save Management

How Necesse stores world saves as .zip files, how to back up, restore, or wipe a world, and how to edit world settings inside the save archive.

Save File Location

Necesse stores each world as a single .zip file:

Platform	Path
Windows	`C:\Users\[Username]\AppData\Roaming\Necesse\saves\`
Linux	`~/.config/Necesse/saves/`

Each file is named after the world — for example, a world named MySave is stored as MySave.zip.

Pass the world name via the -world launch argument. The name must match the .zip filename exactly (without the .zip extension):

./StartServer-nogui.sh -world MySave

If no -world argument is provided, the server will prompt interactively.

A backup is a copy of the .zip file. No special tools are required:

Linux:

cp ~/.config/Necesse/saves/MySave.zip ~/.config/Necesse/saves/MySave-backup-$(date +%F).zip

Windows (PowerShell):

Copy-Item "$env:APPDATA\Necesse\saves\MySave.zip" `
          "$env:APPDATA\Necesse\saves\MySave-backup-$(Get-Date -Format yyyy-MM-dd).zip"

Stop the server.
Copy the backup .zip to the saves directory, naming it to match the world name the server expects.
Start the server with -world <worldname>.

To start fresh on a world name:

Delete the .zip file — the server will generate a new world with that name on next start.
Rename the .zip file to archive the old world — the server will create a new one under the original name.

World-specific settings are stored in worldSettings.cfg inside the .zip archive. To edit them:

Stop the server.
Extract the .zip file.
Edit worldSettings.cfg with a text editor.
Re-zip the contents (the .zip must have the same internal structure — do not add an extra folder layer).
Replace the original .zip in the saves directory.
Restart the server.

Editing worldSettings.cfg while the server is running will have no effect and may be overwritten when the server saves.
