My company is implementing a sharepoint structure of a single hub site consisting of many sites, no subsites. We don't want the presence of folders being in our sharepoint online document libraries. We only want to use document sets and documents. I have already removed the folder option in the "New" menu, and sharepoint designer has prevented users to upload folders into specific libraries through the "upload" menu, however users can still drag and drop folders into document libraries.
When I try to remove the folder content type(0x0120) from the site altogether in sharepoint designer, it states that it could not save changes. I found a way to disable the drag and drop feature, but I still want users to be able to drag and drop documents.
It there any way to remove the folder content type completely from the site?
