Frequently asked questions

    

                    

                How do I convert Overworld coordinates to the Nether?
                
Divide X and Z by 8 and keep Y. To go back, multiply by 8.

            

                    

                Which region file is my base in?
                
Divide block X and Z by 512 and round down: X 1000, Z -250 is r.1.-1.mca.

            

                    

                Can I delete a region file to reset part of my world?
                
Yes. Stop the server, back the file up, then delete it. Those 512 × 512 blocks generate again from the seed.
