I tried to copy a 8GB file to my new 32GB USB flash drive. I encountered the following error: Cannot copy filename: The parameter is incorrect. The issue happens when you try to copy a file larger than 4GB to a FAT32 partition. I fixed the issue by formatting the USB flash drive with NTFS file system with gparted. GParted is a partition-editing application. It can be used for creating, deleting, resizing, copying, and moving disk partitions.
