Now we are going to look at a new networking feature built into Lion and this is called AirDrop and this is how it works. I am going to open a new Finder window. When I do you are going to see an AirDrop entry here. I click on it and you see the name of my computer at the bottom of the window. So what this is, it's a replacement for something called sneakernet. Back in the old days if you had a file and you wanted to give it to somebody who was across the room from you, what you would have to do is you put it on a floppy disk or you'd put it on a key drive and you'd copy it there and you take it over to the person and say, hey, look here is the file that you wanted, instead of e-mailing it or some other method.
Well Lion has its new method called AirDrop and it makes all the sneakernet stuff unnecessary, because now you can easily copy files from one computer to another computer if that computer is within about 30 feet of you. So I have my AirDrop window open. I am going to ask Ian outside the booth to open his AirDrop window and here he is. So, I can see that he's ready to share. Now note AirDrop works only if each computer has the AirDrop window open. I am going to copy a file over to Ian. Open a new Finder window and I will find a document, let's say this Finances file, and I'll drop it on his icon.
I am then asked if I would like to send it, yes I would, I click Send, and I'm waiting for Ian to accept that. When that goes away it indicates Ian has accepted the file and it's been copied to his computer. Now let's see what it looks like when he sends a file to me. Here is file. You hear a little boip! And here is the file that I need and I can choose one or three things. I can save it, if I do this, I will save it will go into my downloads folder. It was something I don't want, I just click Decline or I can save and open.
I will click Save and Open. It downloads and it opens up in TextEdit because this is the host application. Now I want to show you one other thing here. Suppose Ian sends me a file that I can't open. Well let's try that. Ian go ahead and send me something that I don't have a host application for. Here it is. Again I could save it simply, put into my Downloads folder, but I'm going to try Save and Open. It goes to my Downloads folder but a dialog box appears that says there is no application set to open the document Authors.kml. This is a mapping document. So what do I do? I could choose an application, if I think I have an application on my Mac that will open this, or, and I think this is brilliant, I can click on Search Apps Store.
What would happen now is the Apps Store application would open and it would direct me to an application that can open this. At that point I can download the application. I might have to pay for it or it might be a free application. It's a very cool way to get documents you can't open and then immediately find an application that will open them. In this case I am going to click Cancel. And you would want to send that to me one more time and I will just download it. Here it is, I will just save it. It is into my Downloads folder and sure enough here it is. You notice there are two copies because the first time I saved it and then I was prompted to find an application on the App Store. Here's the second copy when I just saved it. Normally you are just going to get the single copy.
And to leave AirDrop all you have to do is close the AirDrop window and your icon will no longer appear in anyone else's AirDrop window. And that's Airdrop in Lion.
