I am using Ubuntu 12.04LTS and I was just going through the applications scope and I saw an application called dolphin and it looked like the home folder(nautilus file manager). So when I opened it the heading was jatin - 'Dolphin'. and it looked like this

enter image description here

Can anyone tell me what it is?

I am new to Ubuntu and I don't know much terms so please try and explain in easy language.

IMO Dolphin is just as good, if not better than Nautilus. You didn't happen to install KDE, did you? – shortstheory Mar 5 '14 at 14:31

A file manager is software which provides a user interface to assist in the organisation of files.

Every file manager provides basic operations such as to create, open, view, edit, search, rename, move copy, and delete files. However, file managers typically come supplied with sophisticated functionality including network connectivity, directory synchronizing, archive handling, advanced searching, shortcuts, file/folder comparisons, checksums, plugins, and more, making them an incredibly powerful tool.

Dolphin is a file manager focusing on usability. You can browse, locate, open, copy and move files with it.

It is the default file manager for the current version of KDE (KDE 4), and can be optionally installed on KDE 3.

Features include:

  • Sidebar
  • Supports dockable panels for places, information, folders and a terminal
  • Breadcrumb Navigation bar for URLs which allows users to navigate quickly through the file hierarchy
  • 3 view modes (icon, list and column) with properties remembered for each folder
  • Split views designed for file copy- and move-operations
  • Network transparency
  • Undo/redo functionality
  • Support of service menus
  • Zoom from 16 x 16 pixels to 256 x 256 pixels
  • Tooltips show previews
  • Thumbnails
  • Panel tabs
  • Renaming of a variable number of selected items in one step
  • Supports: SMB/CIFS, WebDAV, NFS, FTP, and SSH
  • Networked Environment for Personalized, Ontology-based Management of Unified Knowledge (NEPOMUK) integration

In a Nutshell

Dolphin is a file manager, like Windows Explorer. The default file manager on Ubuntu is nautilus from the Gnome desktop. Dolphin is from the KDE desktop. (You'll notice that it uses different icons and colours.)

Many file managers exist, also ones running in the terminal like midnight commander. Those are especially useful when you log in to a remote PC/Server via terminal, i.e. text only.

It's my favorite file manager ... one of the first things I install in a non KDE desktop environment. It's very powerful and configurable.
