Okay, so i installed gta 5 the other night, a bit less than 8 gigs as it said. When i was done I fired it up, all ready to play, then, apparently, i needed to install Addon Packs which had 2 gigs each. One problem. I only have about 4 gigs left on my harddrive, and can only fit 2 of those packs onto there. Would it be possible to put the other 2 onto a different storage unit and still have the game run? or do i need to get one big ol' 16-32GB USB to put it all on? Please help guysh.
