I recommend you to take a look at this explorer file manager
. You can set up your own file server for managing and sharing files through web
browser. It's like DropBox but self-hosted so that you can keep all your confidential files on your own server. The web based UI looks and feels like Windows 7 Explorer. It offers features that are not possible with a FTP server such as zipping files, downloading multiple files and folders in single download etc. It's also easier to set up and administrate than a FTP server.
