Dolphin (file manager)

Dolphin is a free and open source file manager included in the KDE Applications bundle which contains applications used primarily with the KDE Plasma 5 desktop. Dolphin became the default file manager of KDE-based desktop environments in the fourth iteration, termed KDE Software Compilation 4. It could also be optionally installed on K Desktop Environment 3. Konqueror was replaced as the default file manager for KDE SC 4, but is still the default web browser and can be used as an alternative file manager for power users.
