Photoshop is a program that helps you create graphics and photos. It can also be used to make scratch disks. When you save a photo or graphic, Photoshop asks if you want to save it as a JPEG or PNG file. If you choose to save the file as a JPEG, Photoshop will fill in the missing data for you and say your disks are full. If you choose to save the file as a PNG, Photoshop will not fill in the data for you and say your disks are full.
