Main - Check Folder every 5 Minutes

A KNIME workflow to check if a file in a folder has changed and then call a sub-workflow

The workflow will run permanently and check every 5 minutes (you can adapt that) if there has been a change. The last modification date will be stored in a CSV file. If there is no change nothing will happen
