I have a backup with several split .cpk.# files. I didn't know what they were at first, and I just FTPd everything into my PS3. However running it gives me a "data not found; must install" and attempting to install data gives another error. I don't have an external drive to have GAIA unpack it while copying to internal. Is there a way I can extract the files on my PC and then FTP it into the PS3?
