The folder is named based on the categories of the apps you have chosen to place in the folder, but you can customize the name by tapping on
it, and then you will be presented with a keyboard. After the folder is in place, you can tap anywhere outside of the folder to return to the apps
screen, and then drag more apps into the folder. You may have up to 12 apps in a folder, or 16 apps in a folder on an iPad. In iOS 7 and later,
folders can contain an unlimited number of apps, with 9 apps per page.
To reinstall an app, the first step is to delete it, as described at the beginning of this article. After the app is deleted, you can open the App Store
and search for the same app again. Instead of a "BUY NOW" button, you will be presented with an "INSTALL" button since you do not have to
purchase the application twice.
Force Quit Apps
If an application freezes or is not responding, you can force the app to close. To do so, hold the power button until the red slider "Slide to Power
Off" appears. DO NOT slide the slider. Instead, hold the home button for 5 or 6 seconds, and you should be returned to the home screen.
