title: How to get Azure Data Factory to Loop Through Files in a Folder
body: <p>I am looking at the link below.</p>

  <p>We are supposed to have the ability to use wildcard characters in folder paths and file names.  If we click on the 'Activity' and click 'Source', we see this view.</p>

  <p>I would like to loop through months any days, so it should be something like this view.</p>

  <p>Of course that doesn't actually work.  I'm getting errors that read: ErrorCode: 'PathNotFound'. Message: 'The specified path does not exist.'.  How can I get the tool to recursively iterate through all files in all folders, given a specific pattern of strings in a file path and file name?  Thanks.</p>
