konqueror

Konqueror is one of the most advanced file managers for KDE. Thanks to the underlying KDE technologies it can transparently access FTP and SFTP servers, zip files (and other archives), smb (Windows) shares, and even browse and rip audio CDs.

Konqueror is powered by the KHTML rendering engine (and optionally Webkit) which means it supports the latest web standards such as HTML5, Javascript, CSS3, and others.
