Moving Files and Folders
You can move files and folders by right-clicking then pressing move. Here you can enter the location you want to move the files.
If you want to move the files backwards you can use ../
So if your file is in world/config/common and you want it just in config. Put a ../ in the move box. If you would like to move backwards more than once, you can do ../../
This would move the file into the world folder.
