How to Copy A 4GB Or Larger File to USB Successfully?

Why can’t you copy A 4GB or larger file to USB?

To begin, there are two kinds of file systems, FAT32 and NTFS. FAT32 is widely used in different kinds of devices, like hard drive, DVD player, USB and so on. But its biggest disadvantage is that 4GB is the maximum size of a single file while the limitation of a partition capacity is 2TB. NTFS has no such limitation of single files’ size and allows a partition size to be up to 256TB.

If you can’t copy 4GB or larger file to USB, usually, there is with an error message “The file is too large for the destination file system”. And this because that your files are larger than 4GB but your USB is formatted with the FAT32 file system even there is enough free space. Then how to transfer 4GB file to USB successfully? It’s easy! You just need to change FAT32 to NTFS.
