Google is your friend.
I recommend that you use the download manager Jdownloader when downloading from file hosts. By doing so you can avoid all ads and being redirected who knows where, and lessen the risk of having your computer infected with something.
All you need to do is right-click "Copy link location..." and paste it into Jdownloader. You then get a list of files that can be downloaded.
You can filter things by file type or host that you can download from.
