I'm using the below to let the user download to the latest version of my program.
FileUtils.copyURLToFile(URL, new File(directory));
This works fine, however I can't figure out how best to let the user know that the file download is complete. The experience is simply that the program has frozen for a moment, and then the file appears where they asked it to.
The file to be downloaded is a zip, around ~2mb if that matters.
