Konqueror is the free web browser of the K Desktop Environment ( KDE for short ). It can also be used as a file manager , FTP client or file viewer .
overview
origin of the name
The name Konqueror is based on a mind game based on the names of previous generations of browsers: First there was the " Navigator " from Netscape, then the " Explorer " alias Internet Explorer from Microsoft and now the "Conqueror" - Konqueror.
The English word is spelled correctly Conqueror . A K instead of similar sounds has become the hallmark of KDE programs, for example also for the document viewer Okular or the digital photo management digiKam .
Konqueror as a web browser
Konqueror uses KHTML as a rendering engine , the split-off WebKit of which is also used in Apple's Safari web browser and, in the form of the WebKit-split Blink, in Google's Chrome and Opera from version 15. Thanks QtWebKit (since Qt 4.4 ) or QtWebEngine (since Qt 5.4 ) Konqueror but can range from the WebKit or Blink-porting Qt to use as rendering engine. Even with KHTML, Konqueror is an HTML 4.01 and HTML 5 compliant web browser with support for JavaScript (ECMA-262) and CSS2 & CSS3 ( Cascading Style Sheets ) as well as bidirectional fonts such as Arabic.
It supports the secure operation of Java mini programs ( applets ), Netscape plugins for Flash , RealAudio and Real Video as well as SSL for secure connections. The advanced functions include the automatic completion of URIs , the automatic completion of forms, the use of a spelling checker with free choice of language, the ability to import bookmarks from other browsers and the tab navigation familiar from other browsers .
Component structure (KParts)
Konqueror provides an interface through which numerous KDE programs can be embedded as components ( KParts ) using KDE's KParts technology . These components then provide the actual functionality.
In this way the Konqueror provides a file manager for the K Desktop Environment (KDE) with functions for file management. These range u. a. from simple cut / copy and paste operations to advanced searches of the file and directory structure . This is possible both in the network and locally. Directory contents can be displayed in a variety of ways in text and icon display modes. This includes thumbnail previews of file contents. File and directory properties can be easily examined and changed, and programs can be started with a click of the left mouse button.
Since KDE 4 (in some distributions - for example Kubuntu - also earlier) Konqueror has been replaced as the standard file manager by Dolphin , which is specially optimized for file management and is used by Konqueror as a component (KPart) for the file management functions.
KParts can also be used to integrate WebKit for displaying ( rendering ) HTML and SVG files, which improves support for (newer) web standards.
Konqueror is also a full-fledged FTP client, can easily handle Windows shares (provided Samba is installed in the system) and exchange files with a remote computer using the Secure Shell . He can also automatically access CVS repositories with his Cervisia module .
An excellent feature of Konqueror is the ability to divide each window or sub-window two or more times horizontally or vertically. Any content fits into any area. For example, files can be moved between different machines using "drag and drop" or texts and images can be copied from websites.
The Konqueror is a universal file viewer that can display images and other documents of various file formats using a KPart integrated viewer without having to start another program first . This is also achieved by embedding components (KParts) provided by other programs; KView for viewing images, kdvi for viewing DVI files, Kghostview for viewing PostScript documents and various KOffice applications for their respective document types. There is also the option of integrating OpenOffice.org as an engine for document viewing, as some distributions do not use Koffice by default. From version 3.2 of KDE, KSVG also has an integrated viewer for SVG files.
Adaptability
Konqueror can be adapted in many ways to meet user requirements. This affects the general style, the font and symbol sizes, the selection of symbols displayed in the menu bar, the number and space of the toolbars and the definition of new keyboard shortcuts. The various setting profiles can be saved so that they can be accessed quickly when required.
compatibility
The KHTML engine of Konqueror passes the Acid2 browser test from version 3.5 onwards. In the Acid3 browser test, Konqueror version 4.14.2 achieved the full points, but the words " YOU SHOULD NOT SEE THIS AT ALL " can be seen in the upper left corner.

history
Konqueror was introduced in KDE in version 2, which was released on October 23, 2000. Konqueror replaced the KDE file manager (KFM) as the standard file manager. In KDE 4 (released August 18, 2006), Konqueror was replaced by Dolphin as the default file manager . Konqueror continues to offer file manager functionality by integrating Dolphin as a KPart .
