Hello,
I am needing to do exactly this in Nintex(SharePoint 2016 onsite): https://answers.microsoft.com/en-us/msoffice/forum/all/sharepoint-office-365-how-to-update-parent-folder/43b23dce-01e2-4e13-9b0c-d0d719593cef
For whatever reason this is not working in SharePoint designer but I'd rather do it through Nintex anyway.
Thank you for the help!
