Konqueror, is one of the most advanced File Manager for GNU/Linux distributions, especially KDE. Using underlying KDE technologies, Konqueror can can transparently access FTP and SFTP servers, zip files (and other archives), smb (Windows) shares, and even browse and rip audio CDs.
Here is article written by David Both published in open source magazine that describes about Konqueror file manager in detail.
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 Enterprise Linux, Fedora, CentOS, and many other Linux distributions as a part of the KDE Desktop Environment. I find Konqueror an indispensable tool because it can do so many things very well.Konqueror allows you to browse through your files and directories to locate, copy, move, and delete files, as well as to open them using a pre-selected application, or an alternate application.
