Worlds and profiles
Use worlds and profiles to organize your adventures and switch between setups. Check which profile and edition you have selected before making changes.
Back up before experimenting
Close Minecraft before creating a profile archive or restoring one. Keep an additional copy of important saves before testing a new runtime or beta build.
Release and Preview
The launcher supports both editions. Their builds and settings stay separate; run an edition once before changing video settings that depend on its options file.
