World OptionsShare article feedback

The world options are options to manage a world. Internal world settings are handled by game rules.

Java Edition

A world's edit screen.

A player can click on a world to select it, and thereby access the options of it. Then, some options appear at the bottom of the screen.

There are a total of 9 operations that can be performed from the world options, some of which are contained within the "Edit World" screen.

Location	Button	Description
Main Screen	Play Selected World	Loads the selected world. A world can also be loaded by clicking on
	Delete	Permanently deletes the world after confirmation.
	Re-Create	Make a restarted copy of the world. It has the same seed and settings, but without saving any changes made to the terrain.
	Edit	Open a screen with more options:
Edit World Screen	Editing world name	The world name is visible on the top of the screen. A new display name for the world can be inputted. Note that the name of the world folder does not change.
	Reset Icon	Deletes the world's icon.png file, which allows a new icon to be taken. A new screenshot is taken to become the world's icon the next time Save and Quit to Title is clicked.
	Open World Folder	Opens .minecraft/saves/<SELECTED WORLD>/. This allows quickly accessing folders like datapacks along with all the data for the world.
	Make Backup	Makes a new .zip archive in .minecraft/backups/ with the data of the selected world stored. The file name of a backup follows this format: YYYY-MM-DD_hh-mm-ss_<World Folder Name>.zip. Example: 2020-12-24_13-32-00_My World.zip. This is the world called "My World", it was made on December 24, 2020, at time 13:32 (1:32 PM). The world folder name is the original name of the world given at world creation, not the display name.
	Open Backups Folder	Opens .minecraft/backups/.
	Optimize World	Opens a screen to upgrade the level data of the world to the latest format. Once a world is optimized, it is no longer compatible with previous level formats. There are four options: "Erase Cached Data" erases data like light levels and biome data, which must then be regenerated. Create Backup and Load creates a backup to .minecraft/backups/ and then begin the optimization process. I know what I'm doing! begins the optimization process without making a backup. Cancel cancels the optimization process. After clicking either of the buttons, the optimization process begins. Chunks generated in 1.19 or later are skipped, as they use the current format. The rest of the chunks are reformatted.
