Killzone 2 "split" file

I have read a little on the subject of transferring data over 4gb and it being a problem, however I copied killzone 2 to my external HDD. I have other games installed on my internal and it doesn't have split next to them and I have Batman AA copied to the same external and it doesn't say "split", Is there something wrong with the Killzone 2 file that copied that says "split" afterwards?

i fixed with BDEMU2 download and switched to hermes

i got black screen when i want to play killzone 2
when i download it, there 1 file large than 4 gb *.psarc

and i already extract it n put to folder game, when i want to play appear black screen
i already move to internal n select+x , still black screen
can you guys give solution


thanks
