How to find and read log file in FileZilla Server? I have logging turned on already.

For FileZilla Server on Windows computer, log files are located in the "C:\Program Files\FileZilla Server\Logs" folder.

If the log file setting is one log file per day, you can open the log file of a given day like, fzs-2016-10-30.log. The log file entries are easy to read. The example below shows you some log file entries and explanations:

... - (not logged in) (::1)> Connected on port 8090, sending welcome message...
