I was able to get BitKinex to connect. But as far as I can tell, that software does not allow you to map a network drive.
CyberDuck was still giving me errors. It failed to connect to the default directory no matter what I entered.
The best one I have found so far and what I am using now is WebDrive. I just pasted in the URL and it worked. I have a windows drive that I can read, write, create, delete directories and files. The only downside is there is a license fee, currently $47.50. But really easy to configure and use.
