iCloud is a cloud storage and computing service developed by Apple Inc. It secures all of your documents on both Apple and Windows devices. This gives you access to your files on every device where iCloud is installed. To use iCloud, you need iOS 5 or OS X Lion 10.7.5. It is also available for Windows 8 and later. Once your files are in the cloud, you can work on view, edit and share the same file across multiple devices. You can also create new files and folders from iCloud-enabled apps. With iCloud’s automated storage feature, you will always have the latest version of the file on all devices.
