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

== Hints, Tips and Troubleshooting == <!--T:13-->
  
Many selected files looks like this:
+
<!--T:14-->
 +
'''Problem:''' Dolphin's menu entries <menuchoice>View -> Additional</menuchoice> and/or <menuchoice>View -> Panels</menuchoice> don't have any options.  Nepomuk is enabled in System Settings.
  
[[Image:Dolphin folder hovered deselect.png|thumb|240px|center]]
+
<!--T:15-->
 +
:'''Solution:''' Rename the folder <tt>~/.kde4/share/apps/dolphin</tt> (in some distros it will be <tt>~/.kde/share/apps/dolphin</tt>) 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
  
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.
+
<!--T:16-->
 +
'''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''.
  
 +
<!--T:17-->
 +
:'''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. <tt>.xliff</tt> or <tt>.graphml</tt>), 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.
  
{{KDE3}}
+
<!--T:18-->
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.
+
:To solve this issue, you can use [[Special:myLanguage/System Settings/File Associations|File Associations]] to [[Special:myLanguage/System Settings/File Associations#Adding new file types|create an entry for the unrecognized filetype]].
  
{{KDE4}}
+
<!--T:34-->
In KDE 4 Dolphin opens by default, when we click on any folder, it can also be started from [[Glossary#Kickoff|Kickoff menu]].
+
'''Problem:''' Dolphin's Find File service doesn't find files you know are on your computer.
  
== Navigation Bar ==
+
<!--T:35-->
Dolphin integrates a new concept to use the navigation bar in a faster and more precise way. Therefore a breadcrumb navigation bar is used. Instead of displaying the complete path only the navigation points starting from one of the places are displayed as buttons. By clicking one of these buttons you navigate directly to this folder. So you can reach a parent folder from a sub folder in a very quick way.
+
:'''Solution:''' Reindex [[Special:myLanguage/Baloo|Baloo]]. Baloo is a file indexing and search service that Dolphin uses to search for files. It needs to be indexed to workTo solve this problem, in a terminal type, <tt>balooctl check</tt>
  
Between the buttons which represent a folder there is a small arrow which is a button as well. By clicking this arrow a list of all sub folders of the folder in front of the arrow is shown. So you can change very fast the selected and displayed sub folder.
+
<!--T:36-->
 +
'''Problem:''' There is no file transfer dialog.
  
There is also a classical navigation bar which displayes the complete path. To use this style you can select ''"View -> Navigation Bar -> Show Full Location''" or trigger the keyboard shortcut '''Ctrl+L'''. By clicking on the free space next to the last displayed folder in the breadcrumb style you can change to the classical style as well. If the classical style is selected an arrow is displayed at the end of the navigation bar. This arrow is a button which can be used to change back to the breadcrumb style. Of course menu and keyboard shortcut can be used, too.
+
<!--T:37-->
 +
:'''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.
  
== Split View ==
+
<!--T:8-->
Dolphin offers the possibility to split the current folder view so that two folder views are displayed next to each other as known from [[:wikipedia:Midnight Commander|Midnight Commander]]. This is a very comfortable view to copy or move files from one folder to another.
+
Also see [http://forum.kde.org/viewforum.php?f=222 forums] and the [http://docs.kde.org/stable/en/applications/dolphin/index.html Dolphin Handbook].
[[Image:Dolphin split view.png|thumb|240px|center]]
 
  
You can split the view with ''"View -> Split"'' (keyboard shortcut '''F3'''). To change back to only one folder view you can use ''"View -> Close"''. The symbol will show you which view will be closed. Depending on the currently active view the minus sign will be shown in the left or right part of the symbol. In general always the inactive view will be closed. This is important to know if you want to use the keyboard shortcut. There is also a button for splitting and closing the view situated in the toolbar. This button displays the minus symbol  as well, so it is easy to know which view would be closed.

Of course each view has its own navigation bar and each view can use a different view mode.

== View mode ==
+
<!--T:11-->
Dolphin supports three different view modes: ''"Icons"'', ''"Details"'' and ''"Columns"''. These can be changed via the menu ''"View -> View mode"'' or via the keyboard shortcuts '''Ctrl+1''' (Icons), '''Ctrl+2''' (Details) and '''Ctrl+3''' (Columns). There is also a button for each view mode in the toolbar and the context menu of the folder view offers a submenu ''"View mode"'' to change the view mode.

[[Category:File Management]]
Each file and each folder is represented by an icon in the view mode ''"Icons"''. Instead of displaying an icon a preview of the file can be shown. This behaviour can be turned on/off via the menu ''"View -> Preview"'' or via a toolbar button. There exists a size limit for the  file previews. This size limitation can be configured via ''"Settings -> Configure Dolphin -> View Modes -> General"'' option ''"File Previews -> Maximum file size"''. There is also an option to use thumbnails embedded in files.

The files in the currently selected folder are sorted in alphabetical order by default. The way of sorting can be changed via menu ''"View -> Sort by"''. The following sort criteria are available:
 
 
 
* Name
 
* Size
 
* Date
 
* Permissions
 
* Owner
 
* Group
 
* Type
 
Additionally the sorting sequence can be defined by ''"View -> Sort by -> Descending"''.
 
 
 
There is the possibility to display additional information below the icons. These can be turned on/off via ''"View -> Additional Information"''. In principal the same criteria which are available as search criteria can be selected.
 
 
 
You can group the icons to achieve a better overview. This is turned on via ''"View -> Show in Groups"''. Now the icons are grouped and the groups are divided by a horizontal line containing the name of the group as caption. The grouping is related to the selected search criterium.

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.
