how to share the screen on skype

Since the total numbers of the users of skype rises up this year, how many people know the all function tools that skype has? I guess few except the engineers in skype team. So today’s topic is to introduce one simple function of skype which makes video calls effectively and conveniently. Does any one know that the users can share the screen and files even if they are having calls? Which means the person u are contacting with can see everything in your computer, including pictures, music, movies, documents.ect..
 With that function, if the users have any problem of the operating of computers, or can not get the meaning of the alert of company, they can share the computer to opposite side. And he can see the whole content of your computer, view all though the files, and explain the confusion that u ask more visally. But the first step is to download the latest version of skyep. Then connect a person in ur friends list who u can trust most. The last one but no least, press the share button under the dialog box. Is that easy? Thanks to the amazing design, that solve pretty much problem of misunderstandable communication and do a favor to people all over the world.
