You need to provide the downloadable file as a
resource
, usually bound to the
Link component
. There’s different types of resources, so pick the one suitable for your case, depending on where the files are stored.

To force the browser to open “Save As” dialog, rather than displaying the file in the browser (if it’s HTML for example), you should set the Content-Disposition, as done in
this example
. Some discussion about it
here
.

There’s also the FileDownloader add-on, see
this article
