To quote, roughly translated: Onishin, a member of our forums and developer, today gives us a nice homebrew named OpenPS3FTPsplit and is a mod source code of version 2.3 of OpenPS3FTP, the famous FTP server designed by jjolano.
This program has a unique feature that most practical of the split files larger than 4GB on a transfer via FTP. Understand by this that if you want a transfer of these files on the internal hard drive of your console or an external hard drive (FAT32) that is connected, you simply start the copy and the software will automatically split it.
But to avoid splits that you close all your files that you transfer, which could be annoying in the long run, it divides the files in question in each part of 4GB only if the following condition is met: the files you want to transfer must be copied to one of the following destinations (according to it, the homebrew will use the naming conventions or Cobra Multiman):
/ dev_usbxxx / BDISO
/ dev_usbxxx / DVDISO
/ dev_usbxxx / PSPISO
/ dev_usbxxx /
