File is too big for Fat32

Hey guys

I have a 3 file to print in queue that are 4.5 gig , 4.9 gig & 4.1gig
these are huge 75 hours prints on the Phenom L
Fat32 is blocking me big time
is there a SIMPLE work around
i tried cura but i dont understand it and only 10% file reduce wont cut it
I read that you guys were gonna implement Exfat a while ago

Thanks
