I heard the sad news that this website might be shutting down soon. If you're trying to download all you can before it's too late like I am, but you find that you're running out of space on your hard discs, you can always save to the cloud. Install pCloud browser extension to save directly to your account or pCloud Drive as a network drive so it won't take up hd space.

You can get a Premium account ($5 value) for FREE for 1 month here:
