I have modified batch a bit. It is 8xDVD5 still but 100% faster. It takes now about 6.5 hours instead of 13+! You can now choose which language you'd want to use instead to do it manually (they will be copied to %gamefolder%\_Backup). Use setup.exe from post #1.
Note that you need minimum 250GB free disk space for compression.
