hey guys so I've run into this problem after transferring a split pkg of mgs4 from a flash usb now I've tried to merge the 3 files but it cancels automatically without reason or any error codes so I'd like to ask if someone knows what could be causing this cause the first time i did tried to install mgs4 i transfered some of the files to the internal hdd and then it will always happen the same error then yesterday i tried mergin the files from the usb directly and it worked but now that i have the files on the hdd I can't and i would put the whol pkg on the USB to install the game from it but it's only 14 gb aprox so doesn't fit also i don't think it can be the hdd since I've managed to install and play games perfectly

tldr: either how i can solve that multiman won't merge files on hdd or any other ways to merge the files directly on the ps3?
