World Tools

LeviLauncher includes utilities that help you protect and inspect your worlds.

Main world tools

• export a world as a backup package such as .mcworld
• inspect world-related information
• edit selected level.dat fields
• rename a world more safely through the launcher workflow

When to back up a world

Always create a backup before you:

• test Minecraft Preview versions
• install or update multiple mods
• change important world metadata
• move a world between very different setups

Editing level.dat

LeviLauncher can expose selected fields from level.dat for easier editing.

Edit carefully

level.dat is sensitive world metadata. Make a backup first and change only what you understand.

Recommended backup routine

1. Back up before major updates.
2. Back up before introducing new mods or packs.
3. Keep at least one backup outside the version workspace.
