      Large file support

      Ultimate FTP supports two transfer modes: Binary and ASCII. The FTP protocol's maximum supported file size is 2^63 bytes = 9,223,372 TB. However, some underlying filesystems do not support large file size. FAT16 and FAT32 are two examples; they support 2GB and 4GB maximum file size respectively. For other filesystems, see this table

      There is still a workaround for the filesystems that can't store files larger than 4GB. The stream-based file transfer API supports reading file from small pieces and combine them all together to have the large file.
