Big files from PC to MAC

I a mac user and a cinematographer.

I just finished shooting a film on the EPIC and all of the files were transfered onto a Hitachi hard drives formatted for a PC.

I would like to transfer a lot of these files on to my journaled (mac formatted)hard drives. How do I do this? Most of the file sizes exceed 3GB and won't transfer with a FAT formatted drive. Should I get a program that runs windows on my mac to read the files? What about transferring them to the mac formatted hard drive.

To put this question in short. How do I move large files from a harddrive formatted for PC onto a hardrive formatted for a mac?

Thanks
