Dolphin is a file manager for and part of the KDE software compilation. It is the default file manager in the current version, KDE Software Compilation(SC) 4, and can be optionally installed on KDE SC 3. Although replaced as the default file manager for KDE SC 4, Konqueror is still the default web browser, and can be used as an alternative file manager for power users.

Under previous KDE SC versions, Konqueror had served both as the default file manager and web browser. However, for many years users have criticized that Konqueror was too complex for simple file navigation. As a response, the two functions were divided into two separate applications. Under KDE SC 4, Dolphin was streamlined for browsing files, while sharing as much code as possible with Konqueror. Konqueror continues to be developed primarily as a web browser.[3]


Dolphin and KDE 3

As development of the KDE SC 4 version was underway, the KDE SC 3 version of Dolphin was discontinued. However, the program continues to be unofficially available for KDE SC 3 under the slightly modified name of "D3lphin". D3lphin contains many bugfixes and a new sidebar, but is no longer maintained.[4]
