Apple's File Management Solution: iCloud Drive
Currently, storing and managing non-Apple filetypes, such as Microsoft Office files and PDFs, across all of your devices is not a straightforward process and is best accomplished by using third-party applications. With iCloud Drive, to be released alongside iOS 8 and OS X Yosemite later this fall, Apple hopes to simplify the way you store, access and edit files of all kinds across all of your devices.
