hey, I'm trying to copy over a 4GB file from my Mac Pro into a flash drive to use on a Windows machine. As you'll all be aware there can be issues with format when using a flash drive in both a Mac machine and a Windows one, and for some reason I'm getting the message in the title if the file is over 4gb when copying. I presume this to be because the current format only allows for files under a Certain size to be copied to it. however, I'm wary about formatting the flash drive to a different format that supports larger copying capabilities, because I don't know how that's going to fair when I plug it into the Windows machine. I'll be able to copy the file, yes, but then I don't know whether it'll work when I want to put that file on the laptop. Any ideas? Thanks a lot.
