I need to download java don’t i? No you already have it because you’re able to run Minecraft and it needs it too :-)

I am now in Powershell and the only thing i know how to do is Well, you are almost there. You indeed have to run the program from a shell (cmd.exe works fine). Assuming you changed to the directory where the region files you want to process and RegionScanner files are located, and that Minecraft is not running, you’ll do something like:

java -jar RegionScanner-1.03.jar -f path-to-your-level.dat-file -u -o old *.mca

Your previous region files will be backuped to .old files and the modified ones will be readily available.

You can also probably find the commands you issued to Worledit in your local Minecraft client logs, if you want to reverse them with RegionScanner (if possible). Okay, so i am now in a folder with region scanner in it and go from there into powershell. if i type: java -jar RegionScanner-1.03.jar -f path-to-your-level.dat-file -u -o old *.mca It says: ERROR: from parameter does not exist

I'm sorry for not getting it.
