Dolphin is a file manager for KDE focusing on usability.
The main features of Dolphin are:
- Navigation bar for URLs, which allows to navigate quickly
through the file hierarchy.
- View properties are remembered for each folder.
- Split of views is supported.
- Network transparency.
- Undo/redo functionality.
- Renaming of a variable number of selected items in one step.

Dolphin is not intended to be a competitor to Konqueror: Konqueror
acts as universal viewer being able to show HTML pages, text documents,
directories and a lot more, whereas Dolphin focuses on being only a file
manager. This approach allows to optimize the user interface for the task
of file management.
