File too large??

I have an Ultra USB 3.0 64GB. Im trying to transfer a couple video files on to it. One is 53MB, the second is 6.2GB. An error keeps coming  up that the file is too large for the USB. The USB is basically empty, what is going wrong?

hmmmm It would appear your drive is formated as FAT32 and that format only supports files sizes upto 4 GB.  For larger files you need to reformat the drive as exFAT.
