We do not recommend accessing your ownCloud using WebDav with Microsoft Windows because it does not natively support WebDav. Instead, we recommend that you use the ownCloud client for Windows. If you want to use WebDav on Windows, you must use a third-party client like Net Drive, which has a free trial period.
