Right now, I'm getting lines in the log similar to:
. 2019-04-25 11:38:22.740 File: 'Test2.txt' [2019-04-17T16:59:40.189Z] 
. 2019-04-25 11:38:22.744 Copying "Test2.txt" to remote directory started.
. 2019-04-25 11:40:48.250 Transfer done: 'Test2.txt' => '/Test2.txt' 
What I'm looking for is other types of messages or status codes which I might encounter if a transfer is not accomplished. Something like:
Transfer failed: 'test2.txt' file already exists
Is there a list of these codes or message texts somewhere?
