If the FTP protocol is used then only communication via TCP/IP is possible. Furthermore, a number of special considerations apply when FTP servers are used compared to openFT partners. These are for the most part due to limitations in the FTP protocol:
No restart is performed.
Encryption is only possible for outbound requests to an FTP server that provides support for Secure FTP with the TLS protocol. This requires openFT-Crypt (openFT-CR delivery unit) to be installed.
Follow-up processing and coded character sets are only supported locally.
Several file properties are not transferred. For details, please refer to the corresponding „command interface“ manual.
Please note that the other openFT functions (preprocessing and postprocessing, FTAC, etc.) can only be used if openFT is used as the FTP server on the system, where preprocessing and postprocessing are to be performed.
