I have many PDF documents in my site, assigned to the Document File Type by the File Entity Module.
I have added a few fields to the content type, thus allowing nice interface in showing all PDF files on the site, with nice filtering.
Now I want to include Zip archives in this interface. (Zip archives are not by default added to any Document type). I have updated the Document type definition to include the mime type application/zip on this page: /admin/structure/file-types/manage/document/edit
Is there any way I can automatically update the existing zip archive files so they are assigned to the Document File Type? As mentioned, there are quite a lot of them and I'd prefer not to have to upload them all again.
