As a pc user with an ipad you can also use the new PowerToys feature but you're limited to 20 at a time. Or you can follow @azek99 advice. To make it easier open the file explorer and go to the file with the .cube files you need to change. On the address bar (Not the search bar with the little magnifying glass) type CMD. When command prompt opens double check that the path you have matches the file address path. Enter the following command ren *.cube *.cub and press enter The files will all change the file extension, but not the file name.
