Konqueror is an amazingly versatile and powerful file management program that is also a very good web browser and FTP client. It is provided with Red Hat, Fedora, CentOS, and many other Linux distributions as a part of the KDE Desktop Environment.

KDE's Dolphin and Konqueror are no exceptions. It's a complete no brainer to install more contextual menus, so let's do it.
