Deleting foreign language files on Heavy Rain

Hey all, first of all sorry if this is in the wrong section, i'm new here, but still i know someone will know the answer to this. Ok i have a ps3 jailboken, Rogero installed on it, the latest version of Multiman... all that stuff i know all about. One trick i learned about how to free up a little space when copying games to the internal hard drive is to first copy them to an external drive then connect that to a computer so you could view each individual folder and file that made up the game and then just delete all the foreign language files.

I saved atleast 7 gb's of space doing that with The Last Of Us but now i have a problem. I said i know all about jailbreaking but as far as tinkering with the game's files themselves... i'm not so smart there  With TLOU it was easy to see the foreign language files because the files were titled "Japanese", "Spanish", "Danish" etc. but i've now copied Heavy Rain to an external drive and i'm trying to find those files now on my PC to delete them so i can free some space up but none of them say anything about language in their titles. I know they are there because on the menu screen of Heavy Rain you can pick different languages for voices. Yeah so to get to the point... can one of you lovely nerds please tell me where to locate the foreign language files in Heavy Rain and what their titles are so i can delete them? Thanks.
