When checked, Beyond FTP logs a number of significant events for actions generated both locally and remotely. The log file grows indefinitely, and is automatically closed at midnight. Earlier files are deleted based on the Delete Log Files older than value. Note, only earlier files are checked. Beyond FTP will automatically start a new log if the current log is from an earlier day. Older files are examined and deleted each time you start Beyond FTP or close the log.
