With iCloud, you can only access certain files across devices—like iWork files or photos you take on your iPhone.
With SkyDrive, you can access or manage any file from anywhere. It doesn’t matter whether the file is a document, photo, video, PDF, or anything else—just drag files to the SkyDrive folder on your Mac and they’ll automatically be available on your iPhone, iPad, or PC. If you don’t have your devices with you, you can still access, view, or edit any file by signing in to
on any browser.
