How FTP Transfers Files Files can be transferred with FTP in ASCII mode and in binary (IMAGE) mode. ASCII Transfers FTP ASCII file transfers are used primarily for the transfer of ASCII text files. The actual data transfer occurs in 8-bit NVT-ASCII representation. The receiver converts the data from the standardized transfer form to the desired target form according to the target system's internal representation requirements. The end-of-record (EOR) for ASCII transfers is represented by a carriage-return followed by a line-feed. For the MPE XL FTP implementation, ASCII data transfers are used when data is transferred in FTP ASCII mode to or from an MPE XL file of the ASCII file type. Binary (IMAGE) Transfers FTP IMAGE type, commonly called binary transfer type is used for efficient storage and retrieval of files and for the transfer of binary data. The data is sent in a contiguous stream of 8-bit transfer bytes. The receiver is required to store the data as contiguous bytes. For the MPE XL FTP implementation, binary data transfers are used when data is transferred in FTP binary mode to or from a MPE XL file of the binary file type. There is no end-of-record designator for binary transfers. MPE XL File Type vs. FTP Transfer Type Do not confuse MPE XL file types with FTP file transfer types. Using BUILD command parameters, the only MPE XL file type supported is STD. MPE XL files with an ASCII or binary attribute are specified as part of the BUILD command REC= parameter.
