Tip. You can use file:/// in the Vienna "New Subscription..." sheet to specify the path to a local data file when subscribing to a feed. This will read the file and the articles within it as if they were on a remote server. For example, if the file is named rss.xml and is located in your Documents folder, then specify file:///Users/username/Documents/rss.xml in the input field. (Substitute username with your actual user name.)

If you have some process by which the file is being continuously updated then Refresh will read the latest articles and only display those.
