Dolphin
KDE's file manager.
Dolphin is the default file manager on KDE Plasma. It emphasises a configurable interface — split views, an embedded terminal, breadcrumb-style navigation, customisable toolbars — and integrates with Plasma's KIO virtual filesystem for transparent access to remote shares (SMB, SFTP, FTP, WebDAV), archives, and devices. Network shares appear as ordinary directories.
Dolphin replaced Konqueror as the default KDE file manager in KDE 4 (2008). The split was deliberate: Konqueror had grown into a combined web browser and file manager and the developers decided each role was better served by a focused application. Dolphin has been the file manager since.
Peter Penz started Dolphin and the project is now part of the KDE Frameworks release cadence. Many KDE applications embed parts of Dolphin's components: the breadcrumb navigation, the file-information sidebar, and the basic file model are reusable elements across the KDE ecosystem.
