Any options for a Cloud system?  While it just takes a second to do in on prem I don't seem to find a good way to do this.

This would be for HR filing.  We have a form where someone can change a employee's last name.  On submit, workflow goes and find the existing documents, applies the new metadata, and refiles them.  We want to clean up the empty folders left behind.

Short of finding the documents parent folder, then searching again in that folder, then searching up to that parent folder, doing another search to check for results, then up yet another parent folder, etc..
