When trying to connect to AEM (Adobe Experience Manager) using WebDAV on Windows 10 I received the following error:
Add Network Location
The folder you entered does not appear to be valid. Please choose another.
According to this Stack Overflow answer you need to change the value of the following registry key to 2 or more and restart your machine:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
However this did not work for me. I did manage to successfully connect by using a free tool called CarotDAV. Why this works and Windows explorer doesn’t I do not know.
