Install the iCloud app on your Windows computer to make it easy to save and sync files with your Apple devices.
The iCloud app will create folders for iOS apps, including Keynote, Numbers, and Pages. You can also drag just about any type of file including pictures, PDFs, Word docs, etc., into the folder.
If you back up lots of pictures and music files, you may find yourself running short of iCloud storage. You can purchase additional space from your mobile device.
Visit Google Play for the iCloud app for your Android smartphone or tablet.
You can access your iCloud content from any Internet-connected browser, even a computer at the library. Sign in to your iCloud account from a web browser at www.icloud.com.
