Rename and duplicate files in iCloud Drive on iCloud.com
You can change the name of files and folders in iCloud Drive. You can also create a copy of a file by duplicating it.
Note: You can’t change the names of app folders, such as Pages, Numbers and Keynote.
Rename a file or folder
In iCloud Drive on iCloud.com, select the file or folder, then click in the top-right corner.
Click Rename, enter a name, then press Return or Enter.
Duplicate a file
In iCloud Drive on iCloud.com, select the file, then click in the top-right corner.
Click Duplicate.
The duplicated file appears in the same folder as the original, and it has the same name with a number added to the end. For example, if you duplicated a file named “Personal Budget,” the new file is named “Personal Budget 2.”
You can save it with a new name, as described in the task above.
