With iCloud you no longer have to fuss with traditional computer files and folders or worry about forgetting where you put a document when you go back to look for it later. For apps that support Documents in the Cloud, all you have to remember is which app (or apps) opens the type of file you want to work on. From then on, iCloud manages everything, storing any changes you make back up to the server, and pushing down those updates to every device you have logged into your account. Create a Keynote presentation on your iPad at home, get to work and it's ready and waiting for you on your iPhone.
iCloud-enabled iPhone, iPod touch, and iPad apps will automatically use Documents in the Cloud to save your files, provided you've turned it on.

That's it. Your file will now be uploaded to iCloud and accessible via Pages, Keynote, and Numbers.
