Based on your description this is more RPA than RDA, since there is no user initiated action and no user involvement is required. Anyway, you can set up endless loop or (preferable) initiate periodic checks of file content with Timer ticks and send e-mail with SMTP component or Outlook connector.
Are you having any particular issue in mind which you are not sure about?
Thanks Jeff for your suggestion , We will use the same in our solution design. Additionally the solution will create cases based on the inputs from the files and act as producer BOT , whereas the consumers are deployed as RPA. kindly review and revert if the producer solution can be deployed as RDA in local machine.
