To delete a document type, there cannot be any existing Contentverse documents saved using that document type. This applies to the active Contentverse Room as well as in the Recycled Documents tab in Administrator . Once all documents for that document type have been removed, you can delete the document type by launching Administrator , connecting to the target room and under the Document Types tab, selecting the Delete button.
If an index is not being used by any other document types, you will also be prompted to delete each index that belonged to that document type. Here you can say no if you plan on using that Index for additional Document Types.
