MCA Selector is a desktop GUI application for selecting, deleting, and exporting chunks and regions from Minecraft Java Edition world saves (.mca files). It is built in Java with JavaFX and ships installers for Windows, macOS, and Linux.
Use cases
- delete unwanted chunks from a Minecraft world save
- export selected regions of a Minecraft world to a new file
- reset chunks so they regenerate with new game versions
- trim a huge Minecraft save to reduce file size
- visually browse a Minecraft world's chunk grid
- merge or import chunks between Minecraft worlds
When to choose
- you need to surgically remove or export chunks from a Minecraft Java Edition save
- you want a visual GUI instead of editing .mca files manually
- you need to prepare a world for a Minecraft version update by regenerating chunks
When to avoid
- you play Minecraft Bedrock Edition rather than Java Edition
- you need in-game world editing rather than save-file manipulation
- you are unwilling to back up your world, since the tool permanently deletes chunks
