Delete files in iCloud Drive on iCloud.com
You can delete files you no longer want to store in iCloud Drive.
In iCloud Drive on iCloud.com, select the files you want to delete, then click
in the iCloud Drive toolbar.
Files you delete from iCloud Drive are recoverable for 30 days, but you can remove deleted files before the 30-day time period is up. See Recover deleted files on iCloud.com and Permanently remove deleted files on iCloud.com.
Note: Files in the Recently Deleted folder don’t count toward your iCloud storage.
