GBZ files? Or you mean CBZ? What Library? I don't know how to do any of the above let alone script. But thanks for the recommendation. To Jon @jon I tried that cbx convertor but it freezes up and wont let me convert anything. Its a program that shrinks book and comic book files (cbz, cbr etc) in batches. As I said earlier, it won't let me do it and when it does work, it can't handle more than one. It freezes up and restarts so I'm unable to use it on my computer. Again, I'm not a programmer so I wouldn't kno what else to provide you guys with. I know that cbr and cbz are just zipped files renamed. I saw this post a while ago and dmed the programmer but he hasnt responded as of yet.
