Instead of travelling thousands of blocks in search of copper or geodes, you can trim the unused chunks and have new features, right on your doorstep. Thanks to a nifty little program called Amulet, trimming your world is a relatively simple process. Follow the guide below to trim bedrock or java edition worlds.

Warning: Before following this guide, make a back-up of your world.
