I have moved my library all around to various laptops/desktops to have a back up of my library but never from a windows 7 computer to a windows 8 computer. The problem is that I transferred everything just fine but the computer assigned the json file to some icook program that isn't even downloaded to the computer, ugh! So the question is how can I change the assigned program to open the file to Calibre and not the stupid icook program?
