Restrict document set

Question

when I create a document set, I only want certain document types to be created (see screenshot).

How can I restrict the fact that only Word files can be created in the document set?

Best regards

Answer 1

Per my test, when I don't add document set content type into the document library, there are four file types to choose.

When I add document set content type into the document library, there are two file types to choose. You could disable folder in the advanced settings.
