I am in the process of organizing my companies website. There are a lot of unnecesary files up there, and I am in the process of getting rid of them. One thing I have noticed is that each folder has a folder inside it called "_vti_cnf". This folder is an exact replica of the folder it is housed in. What is the purpose of these folders? I downloaded the entire site and did a local test by deleting every "_vti_cnf" folder and the page still worked fine. Can you think of any reason for these folders being there?
