Probably a stupid question, I'm trying to find the best way to see where Nintex forms are being used. I see in analytics I can find where the workflows are being used but not the forms. Am I missing something?
Really good question. I don't know of an exact method that would help you, but you can find the XML forms in the 'hidden' Nintex Forms library.
Navigate to the above and a document library will open with the XML form saved. It doesn't tell you which one belongs to what location, however opening it should give you an idea.
