A simple GUI and command line app to prune chunks from a Minecraft Java Edition world.
Make sure you have a backup of your world!
We are not liable for data loss!
- Java 17
There are two ways to use this application: GUI mode and CLI mode.
The GUI mode offers an easy way to tweak the different parameters of the application.
To use the GUI, open the WorldPruner.jar file with Java.
You simply need to open your world folder with the file chooser, provide a minimum time, a radius and an optional whitelist containing all chunks that should be kept in any case.
The CLI mode is meant for server owners, to prune their world without needing to download the world first. This mode allows to operate the application from the command line.
Command line arguments:
| Argument(s) | Default Value | Description |
|---|---|---|
--world -w |
Required | The path to the world folder |
--time -t |
0 seconds |
The minimum time a chunk should have to be kept |
--radius -r |
0 |
The radius of additional chunks preserved around matching chunks |
--white-list -W |
The path to whitelist CSV file | |
--continue-on-error -c |
If execution should continue if an error occurs | |
--white-list-only -l |
Prune everything except the whitelist, requires --white-list to be set |
|
--debug -d |
Enables debug logging to the log file, also works for GUI mode | |
--help -h |
