At first look, this is a simple file manager, but it has many talents. Some features include:
  
When we open the dolphin from K-menu it shows starting directory - by default it is your home directory. That's the place in system, where all your files are kept. You can write your files outside of this folder, but all applications are configured to propose this folder as place to write your files to. And this is easier, when you are keeping your things here.
+
<!--T:5-->
 +
:* Split windows - view and use two directories at the same time
 +
:* Viewing attributes can be set (and remembered) independently for each window
 +
:* Tabbed browsing
 +
:* Use the optional informational panel on the right
 +
:* Or elect to have essential attribute information displayed in the window
 +
:* Use 'breadcrumb' navigation for speed
 +
:* One-click change to editable navigation bar
 +
:* Add Folders panel for traditional navigation
 +
:* Add a terminal in the directory you are currently browsing
 +
:* Many functions controlled by keyboard shortcuts
  
To open file, or go to folder just click on it. You don't have to double-click. It's KDE, not windows - you can click only once :).

Selecting files - in KDE, by default when you click once on something, it activates. In Windows you have to couble-click for that effect. So, there is problem, what to do in KDE if you don't want to open folder or file, only select it ? Answer is simple - over any icon in dolphin, when you hover your mose over it, there will be small "+" sign. Like that:

When you click that sign, this file/folder will be added to selection. You can easily select many files in that way (selecting by draging rectangle also works).

'''Problem:''' When I choose the application to open a specific filetype with, it seems to affect other filetypes too. It’s like '''Dolphin''' cannot tell the difference between the ''two different filetypes''.
  
We also see here, how we can deselect files - when file is selected, and you place your mouse cursor over it, in place of "+" sign there will be "-". If you click it, file will be deselected.

:'''Solution:''' Probably the KDE platform does not know about one of the two filetypes, so it associates the filetype to a different, known filetype.

You can split view in Dolphin, to make it easier to copy between folders, etc.

It will look like in old Norton Commander or Total Commander (or Midnight Commander).

D3lphin is a fork of Dolphin for KDE 3. It lacks some features of Dolphin from KDE 4. It is also less known, because for KDE 3 default file manager was Konqueror. This fork is not supported by KDE and is no longer maintained by its author.

At first look, this is a simple file manager, but it has many talents. Some features include:

  • Split windows - view and use two directories at the same time
  • Viewing attributes can be set (and remembered) independently for each window
  • Tabbed browsing
  • Use the optional informational panel on the right

Tutorials

Hints, Tips and Troubleshooting

Problem: Dolphin's menu entries View -> Additional and/or View -> Panels don't have any options. Nepomuk is enabled in System Settings.

Solution: Rename the folder ~/.kde4/share/apps/dolphin (in some distros it will be ~/.kde/share/apps/dolphin) and restart dolphin. This will purge your dolphin customizations but the entries should be back. If everything works as expected you can then delete the folder. This happened to me after an upgrade from KDE 4.4 to 4.5

Problem: When I choose the application to open a specific filetype with, it seems to affect other filetypes too. It’s like Dolphin cannot tell the difference between the two different filetypes.

Solution: Probably the KDE platform does not know about one of the two filetypes, so it associates the filetype to a different, known filetype. This is common with XML-based filetypes; even if they use a file extension of their own (e.g. .xliff or .graphml), if they are not a filetype known by the KDE platform, they will be treated as any other XML file, and opened with the default application to open XML files.
To solve this issue, you can use File Associations to create an entry for the unrecognized filetype.

Problem: Dolphin's Find File service doesn't find files you know are on your computer.

Solution: Reindex Baloo. Baloo is a file indexing and search service that Dolphin uses to search for files. It needs to be indexed to work. To solve this problem, in a terminal type, balooctl check

Problem: There is no file transfer dialog.

Solution: As of KDE 5 jobs like file transfers are handled by default in centralized notification system; file transfer is also shown in task manager. To enable separate file transfer dialog disable file transfer tracking on both the System Tray notification area and the task manager plasmoid and re-login.
