The description of Downloader by AFTVnews
Downloader allows Android TV owners to easily download files from the internet onto their device. You can enter a URL which directly points to a file, or you can sideload the web browser plugin to download files from websites. The browser plugin supports remotes and game controller, so a mouse and keyboard is not necessary. The browser plugin can also be used for general web surfing with fullscreen mode, zooming, and quick access to favorites/bookmarks. Favorites allow you to easily save and open frequently visited URLs. Once files are downloaded, you can use the app's basic file manager to open them, install them if they are APK applications, or delete them.
