Konqueror is a free and open-source web browser and that provides web access and functionality for file systems (such as local files, files on a remote FTP server and files in a disk image). It forms a core part of the KDE Software Compilation. Developed by volunteers, Konqueror can run on most Unix-like operating systems. The KDE community licenses and distributes Konqueror under GNU GPL-2.0-or-later.
The name "Konqueror" echoes a colonization paradigm to reference the two primary competitors at the time of the browser's first release: "first comes the Navigator, then Explorer, and then the Konqueror".
It also follows the KDE naming convention: the names of most KDE programs begin with the letter K.
Konqueror first appeared with version 2 of KDE on October 23, 2000. It replaces its predecessor, KFM (KDE file manager). With the release of KDE 4, replaced Konqueror as the default KDE file manager, but the KDE community continues to maintain Konqueror as the default KDE web browser.
