On Formatting, “NTFS maximum theoretical limit on the size of individual files is 16 EiB (16 × 10246 or 264 bytes) minus 1 KB, which totals 18,446,744,073,709,550,592 bytes. With Windows 10 version 1709 and Windows Server 2019, the maximum implemented file size is 8 PB minus 2 MB or 9,007,199,252,643,840 bytes.” Please note that Windows 2016 Server are having these limitations, also.
