Multiman uses this naming scheme for split files.
This method uses Linux's built in “split” command to split the file at every 4,294,967,295 bytes, add a 5 digit suffix at the end of each part, and give the suffix a starting number value of 66600. PS3's don't natively support NTFS and would require additional setup. Most PS3 owners know that on FAT32 volumes, a single file bigger than 4,294,967,295 bytes won't copy to the volume due to the limits of the FAT32 format. Getting 4gb+ pkg files on a PS3 for installing can be time consuming. Just the terminal in Linux (or Mac's?) using the built-in “split” command. This tutorial is to help intermediate terminal users split files into 4gb parts without using any proprietary software.
