Deleting empy folders in Sharepoint Online using Powershell CSOM

starting from this post

I propose you following script

It will search all folders and subfolders  and if some of folders doesn’t contains files it will shows you these folderfs and it will ask you if you would like to delete them or not.
For any issue or question don’t hesitate to post a comment.

This script can be useful to search for empty folders and delete them, in a library located on a Sharepoint Online tenant
You need to know 2 mandatory parameters:
– $SiteCollectionUrl     : the URL for the site collection
– LibraryName           : the name of the destination libraryCopyRight
This script can be use as it is or can be changed based on your needs. For more details please feel free to contact me
