Hello,
I would like to suggest that when you upscale a lot of images that are on folder and you will like it to make it better or easier that the program will create a folder inside the with the new images inside the original folder. That will make it easier to just to transport the upscale file easily and it is already on one place. Because I always create a new folder for the upscaled images instead of deleting the old ones or need to transport them.
