You'll want to take a look at requests (to fetch the html and the file), Beautifulsoup (to parse the html and find the links)

requests has built in auth: http://docs.python-requests.org/en/latest/ Beautifulsoup is quite easy to use: http://www.crummy.com/software/BeautifulSoup/bs4/doc/

Pseudocode: use request to download the sites html and auth. Go through the links by parsing. If a link meets the criteria -> save in a list, else continue. When all the links have been scrapped, go through them and download the file using requests (req = requests.get('url_to_file_here', auth={'username','password'}), if req.status_code in [200], file = req.text

If you can post the link of the site you want to download from, maybe we can do more.

You can use selenium web driver to automate the downloading. You can use below snippet for browser download preferences in java.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.manager.showWhenStarting", false);
profile.setPreference("browser.download.dir", "C:\\downloads");
profile.setPreference("browser.helperApps.neverAsk.openFile","text/csv,application/x-msexcel,application/excel,application/x-excel,application/vnd.ms-excel,text/html,text/plain,application/msword,application/xml");

To handle the popup using this class when popup comes.

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_DOWN); 
robot.keyRelease(KeyEvent.VK_DOWN);
robot.keyPress(KeyEvent.VK_ENTER); 
robot.keyRelease(KeyEvent.VK_ENTER);
