Hi there and welcome
You will need torrents in order for it to be useful. So what you need to do is find sites that supply Torrents, such as https://thepiratebay.se/
There you can locate Torrents that can be downloaded within this downloader.
I would advise to be wary of downloading content and ensure it is only used for legal content as we do not condone using it for any illegal activities, especially if it violates copy write laws.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
