The pain point for me with Windows Explorer as a WebDAV client (or as an FTP client) is that downloading large amounts of files usually results in Windows calculating transfer times and Explorer freezing.
Given that, what is the best free WebDAV client for Windows?
I think something like Filezilla, but for WebDAV, would be ideal.
