Well, I have just downloaded the game Bleach: Blade Battle from BT. It has four splitted files, which have no extension. The extension of each of them is iso.000, iso.001, iso.002, and iso.003. I tried all the program but they don't work with it. I even try hjsplitter to join them, but the hjsplit only joins there files iso.001 - iso.003. It doesn't join the iso.000. I need some help with it. I heard there is a way to join them via cmd or the command prompt. But I just don't know how.
