Once the synchronization finishes you get a message "Operation was successfully completed. Connection was closed." with an option "Never show this message again".
If you check it, WinSCP will exit automatically the next time.
I am using the current version of WinSCP on Windows 7 to sync files with an FTP server. The sync occurs without issue but I would like the application to exit upon completion of the operation. During a transfer I see that I can manually change the "Once Finished" to Shut Down, but I believe that will shut down my computer, which I do not want. I would like the software to simply exit upon completion by default each time a session is run. Is that feature available?
