Yes, the following logging configuration will write two log-files: one (Summary.log) containing only log message of level INFO and lower, and the other (Verbose.log) containing all log messages being logged by CompleteFTP regardless of the level . Keep in mind that CompleteFTP has its own internal log level, so if that's set to INFO or lower then Summary.log will be identical.
The following logging configuration should be saved in a file called LogConfig.xml and saved in C:\ProgramData\Enterprise Distributed Technologies\Complete FTP\Logs:
