Flash Saver is a utility that adds a new option to the context menu in your Web browser, saving Flash files contained in the Web page you are visiting such as YouTube.
The option appears when you right click on any part of the page that IS NOT Flash animated (so don't click on the video basically) and click "Save Flash In This Page". Once activated, the program lets you view all the Flash files on that particular page, download conveniently selecting the desired files and even classify them by type i.e. games, movies, introductions, etc. In small files, it's not an issue but as the size of your downloads increase, you'll need to use the multithread option which allows you to make multiple connections to the same file which basically means, it downloads twice as quick. All in all, the program is easy to use and especially on big downloads, offers some significant speed advantages.
This is definitely a more professional approach to the Flash downloading genre although the downside is that it's not free.
