Which semantics does the File Sender Adapter apply to determine which files to retrieve from an FTP server?
Up to and including XI 3.0 SP13 the File Adapter will issue an NLST command (see RFC 959) with the configured source file name scheme as first parameter to the FTP server. It will try to retrieve any of the files returned by the FTP server in response to this command. Starting with XI 3.0 SP14 / PI 7.0, the File Adapter will issue a LIST command with the configured source file name scheme as first parameter to the FTP server. If it is able to parse the returned result (which is the case for UNIX- and Windows-style directory listings), it will retrieve any of the returned files. If it cannot parse the result, it will fall back to the pre-SP14 implementation and use the NLST command as described above. 28.
