Upload a Minecraft .dat, .mca, or ship .json file to inspect, repair, and download edited data.
Uploads are stored as temporary working files. On a public site, local paths only exist on the server, so raise the server upload limit for large browser uploads.
Choose an old region and a new region, then select chunks from the old file to copy into the new file.
For large `.mca` files, paste local paths instead of uploading.
Use this when one region has the chunks you want and another region is where those chunks should live.
The next screen lets you choose which source chunks are moved into the target region coordinates.
