How to Add Files to an iPad
Certain apps for the Apple iPad support a service called file sharing, which allows you to transfer documents between your device and your PC or Mac computer. These apps include Pages, Keynote and Numbers, which are all part of the iWork suite for the iPad. To start adding files from your computer to your iPad, you must configure file sharing through iTunes while your iPad is connected to your computer.
Plug your iPad into your Mac or PC computer using an iPad USB cable.
Open the "iTunes" application.
Highlight your iPad from the "Devices" list on the left side of the window.
Go to the "Apps" tab at the top of the window.
Scroll down to the "File Sharing" section, and highlight the app that you want to use to transfer files.
Click the "Add" button.
Select the files that you want to add to your iPad, and then click "Choose."
Click the "Sync" button to save the settings and start transferring the selected file to your iPad.
