Are you tired of renaming your files because of a huge renaming in the textures? then use this tool!
This batch file will automatically copy/rename your textures to support 1.13.
There's 2 modes, Dual-Support (To support 1.12 and 1.13) and Total Conversion (To support only 1.13).
Note: The modes are separate files.
How to use it:
1. Put this file in the Resource Pack's root directory (1.12 or below).
Note: Only works in Resource Pack folders.
2. Run this file.
3. Press any key to confirm the script execution.
