What is iCloud Drive?
With iCloud Drive, you can securely store your files in iCloud and access them on iCloud.com using a web browser.
On iCloud.com, you can use iCloud Drive to upload and download files, share files, delete files, organise files in folders, rename files and recover recently deleted files. You can also share folders of files with other iCloud users. If you have Pages, Numbers or Keynote files stored in iCloud Drive, you can view them in a web browser on your iPad, but you cannot edit them. See Pages, Numbers and Keynote on iCloud.com.
To use iCloud Drive on iCloud.com, go to icloud.com/iclouddrive and sign in using your Apple ID. Make sure to use a browser recommended in the Apple Support article System requirements for iCloud.
