If you used the iCloud Documents and Data service, you need to turn on iCloud Drive to see your files. When you switch to iCloud Drive, the amount of storage space your saved files use in iCloud doesn't change.
What is iCloud Drive?
iCloud Drive allows you to easily store, access, and share files with friends and family. Documents that you store in iCloud Drive stay up to date across all of your devices, and you can access them from your iPhone, iPad, iPod touch, Mac, or PC, and on iCloud.com.
How to set up iCloud Drive
Follow these steps to turn on iCloud Drive on your devices and on the web. You can then access your files on devices with iOS 8 or later, Macs with OS X Yosemite or later, PCs with iCloud for Windows 7 and later, and on iCloud.com. If you use an iPhone 4, you can access iCloud Drive on iCloud.com via Safari.
