I have a workflow where I take the input from one folder, and then output it to another older using a run command and "if not exist" command, the error occurs when there are no files in the input folder. I want to be able to send an email if no files are found but the run command does not allow the email to be sent? I also use another run command at the end of the workflow to compress the output folder. How do I resolve the errors for both these run commands?
