Konqueror is much more than a web browser. You can use it to access local and remote files using many different protocols.
Konqueror is the file manager for the K Desktop Environment (KDE). It supports basic file management on local UNIX filesystems, from simple cut/copy and paste operations to advanced remote and local network file browsing.
Konqueror is the canvas for all the latest KDE technology, from KIO slaves (which provide mechanisms for file access) to component embedding via the KParts object interface, and it is one of the most customizable applications available.
Konqueror is a universal viewing application, capable of embedding read-only viewing components in itself to view documents without ever launching another application.
