Apple Merging ‘iCloud Documents and Data’ Service With iCloud Drive in May 2022

Apple prepares to combine its iCloud Data and documents service with iCloud Drive beginning in May of 2022, according to a support document released late last week (via MacGeneration).
iCloud Drive and iCloud Data and documents share the fundamental ability to backup data from apps. ICloud Data and files was typically a troublesome, confusing experience. On the other hand, iCloud Drive is more unified, with users able to access their files and content through the Files app across all their devices.
As Apple explains, starting in May of next year, users who are using iCloud Data and files will have their accounts instantly migrated to iCloud Drive. Users should by hand enable iCloud Drive to see their files once the merger takes place.
In May 2022, the iCloud Data and files service, our former file synchronization service, will be disturbed and completely replaced by iCloud Drive. If you utilize iCloud Documents and Data, your account will be migrated to iCloud Drive after that date.
You should activate iCloud Drive by following the actions below to view your files if you use the iCloud Data and documents service. Updating to iCloud Drive does not alter the storage space utilized by your files saved in iCloud.
iCloud Drive launched in 2014 as a combined, smooth way for Apple users to keep all their files, documents, and more integrated throughout all their devices. To activate it, users on iOS or iPadOS gadgets can go to Settings -> > iCloud and allow iCloud Drive, or through System Preference -> > iCloud, and choose iCloud Drive on macOS.
