I'm looking for a way to add a notification file that says that files have been uploaded/downloaded via a WinSCP script that already runs. We have a script that get's files from our network location and uploads them to a SFTP server. Since this script runs every 10 minutes, there is not always a file to upload/download. However, when the file(s) are uploaded/downloaded, we would like to add a confirmation string that shows that. How or can we do this?
