NBT Studio can be used on a Minecraft server to edit the files and properties of a world. This is a handy tool for server administrators to assess and fix issues with mods and general server issues. NBT Studio allows users to edit normally inaccessible files, such as item overrides that can cause connection issues on modded servers. Before attempting to make any changes to a world, make a backup file of the world to ensure no errors occur and progress can be saved.

Note: Make backups locally to save any necessary files.
