We have one workflow form wherein we have placed buttons that will allow creating and opening of workflow forms, when they open it the first time and also there are view buttons so that they can open a form they have already created. Sometimes users go and create forms outside the workflow form , directly from the respective form's SharePoint library. Is it possible to disable the creation of new forms from this library? Is it possible to disable the NEW button from the respective form's SharePoint library?

A quick Google search tells me that this is rather complicated. Please read the following:
