Different programs will use some native file types that are not usable in other programs. This is often a question that is asked of PaintShop Pro users who find Photoshop supplies. Can I use them? Some file types are commonly used in most graphic programs (ex: .jpg, .png) while others might be usable in a limited number of programs even though they are native of one (ex: .psd files that are Photoshop format but can be used by PaintShop Pro). Yet, at other times, some files need some tweaks to be used in a different program.
