You could map a windows drive to the library and have people access it from there. From a windows explorer window, use the ‘Map Network Drive’ ‘Connect to a Web site that you can use to store your documents and pictures’ option. Create a page that describes how to do that, or somehow push that out to others..
Make sure the WebClient service is running:
In Windows, go to Services and look for the WebClient. Make sure it is set to start automatically on reboot.
Workaround – start the service manually by using it. Open up an Explorer folder and navigate to NAMEOFYOURSHAREPOINT@SSLDavWWWRoot . That will start up the WebClient.
