The FAT16, FAT32 and NTFS file size limitation


The file size limitation appears to be the problem,
but the maximum size depends on the operating system.
What is the size of the file you're copying and where does it reside?

The maximum file size on a FAT32 formatted partition is
4 GB or 4,294,967,296 bytes minus 2 bytes ...

The maximum file size on a FAT16 partition
under Windows 9.x and ME is 2 GB minus 1 byte ...

But the size limit using the FAT16 file system
under Windows NT or 2K is 4 GB ...

And the NTFS file system has a (theoretical) maximum file size of
16 exabytes or 18,446,744,073,709,551,616 bytes (2^64 sectors) ...
