File Browser Tool on Zenworks 11.4 Appliance

Just upgraded my Zenworks appliance from 11.3.2 to 11.4 (and then applied 11.4.1 upgrade). The original appliance had a gui File Browser tool that allowed me to connect to Windows shares and thus could easily copy files and folders from Windows computers to the content-repo on the appliance. Unfortunately, either this tool is not included on the new 11.4 appliance, or I just don't know how to find it. Not being expert at running linux commands, I would appreciate any help you can provide. I either need some reference documents on how to use linux commands to copy folders & files from windows file system to the appliance, or even better, how to get a GUI tool similar to the one that was on the 11.3 appliance.

By the way, I've tried using the "Terminal and File Explorer" that is on the ZENworks Appliance Administraton web page but it does not support folders -- just files.
