Access documents, music, videos and photos with Amazon Cloud Drive. This official cloud-storage service offers an easy-to-use interface, and the software automatically arranges all your files into specific categories like music or movies. Compatibility with Kindle lets you access your documents on an Amazon e-reader. The simple interface shows you how much storage you have available, letting you easily ensure you don't run out of space. Upon downloading the program, you'll begin a three-month trial. Once the trial period expires, you're presented with a variety of subscription options. In order to run this application, you need a device with Android 4.2 or higher.
