title: Specify default download folder - possibly with JavaScript?
body: <p>We're currently in the process of developing a web-based application which will require the downloading of files through the browser. It would be ideal to have these files end up in a specific location on the file system.  </p>
  
  <p>Is there a way to make the file save and file open dialog default to a specific folder, such as <code>%USER%\Downloads\MyApp\</code>?     </p>
  
  <p>I don't want it to be a forced thing, but if we can get it to default to the desired location, it would at least be a good prompt for the user, and provide a better experience with other portions of the application.  </p>
  
  <p>I'm sure this can be done with a Java control, but it would be nice to be able to do it with some simple JavaScript or something instead.</p>
