16 GB cruser blade problem

I have some movies of 5 gb on my pc. When i copy it to pen drive it gives the message disk is full. While the capacity of the pen drive is 16 GB. If i try to copy small files like of 1-2 gb it works fine. I tried copying small files up to 14 GB it worked fine.

I don’t understand the reason.

the reason is that the drive is formatted in FAT32. FAT 32 has a single file size limit of 4GB. here is a FAQ about the issue.
