Folders

                                                          A new way to organize your apps.

Make room for more apps. 


    Thanks to the App Store you can choose from over 350,000 apps and games. But these apps can fill your iphone Home Screens pretty quickly. That’s where the new Folders feature comes in. It gives you an easy way to keep your apps organized and declutter your Home screens. And you can launch your favorite apps with a couple of taps.


Creating a folder is easy.


    To create a folder, touch and hold an app until it wiggles, drag it onto another app, and you’re done. You can repeat the process with more apps. For example, you can put all the games your daughter plays in one folder, all your news apps in another, and all your productivity apps in yet another. You can also create folders and organize apps using iTunes on your Mac or PC, then sync it all back to your iPhone.

   Naming your folders — it’s automatic.


   iPhone automatically assigns a name to your folder based on the category of the apps inside it: Games, News, Sports, and so on. Of course, you can change the folder names to whatever you want, such as Katie’s Games or Baseball Apps.


 

Download apps to your heart’s content.


    You can have up to 180 folders on your iPhone. And since each folder can hold 12 apps, that means you can keep up to 2160 apps organized on your iPhone at any time. Which is a great way to use all those gigabytes of storage available in iPhone 4.
