Summary
Minecraft Region Fixer is a free utility for finding problems in Minecraft region files and world folders on Linux, macOS, and Windows. It can replace corrupted chunks with chunks from an older backup, or remove them so Minecraft can generate replacements when no backup is available. It also scans level.dat and player .dat files and reports warnings, but does not repair those files. Other uses include replacing regions from backups, removing entities, and investigating world problems. The command-line program runs with Python 3.x; it does not work with Python 2.x. Options let users set the number of scanning processes, write detailed results to a log, and delete broken chunks, region files, or excess entities. Those deletion options can alter a world, and the project warns that bugs may exist and recommends making a backup before use. It supports Minecraft region files (.mca) and world folders, and is licensed under GPL-3.0.
Who it is for
It suits Minecraft players who want to inspect or repair region files and are comfortable running a Python command-line program. Users who need to recover files should have a backup where possible.
