== Dolphin or Konqueror? ==

Dolphin is the file management application of Plasma Workspace. It is designed to be simple to use, yet powerful.

[[Special:myLanguage/Konqueror|Konqueror]] was the default file manager in KDE 2 and 3, and is still available for those who prefer its interface. It is a web browser, a file manager, media viewer and more. For file management it uses the Dolphin KPart, and so has all of the functionality of Dolphin.

==Discover Dolphin==

The first section takes you on a guided tour of '''Dolphin'''. The second section deals with the concepts of different types of bookmarks.  The third section discusses archive management.  Finally we look at 'More Cool Things'.  The images are clickable - you can see the enlarged view.

===Introduction to Dolphin===

'''Dolphin''' is the file manager of the KDE Software Compilation.

I'll show how to use '''Dolphin''' for common file managing tasks, and how to customize it to your needs.
[[Image:Dolphin_Plasma5_thumbnail.png|thumb|240px|center]]
When we open the '''Dolphin''' from the [[Special:myLanguage/Plasma/Kickoff|Kickoff menu]] it shows your starting directory - by default it is your [[Special:myLanguage/Glossary#Home_Directory|Home directory]].

To open a file, or go to a folder just click on it. (This can be changed to double-click in <menuchoice>System Settings</menuchoice> &rarr; <menuchoice>Desktop Behavior</menuchoice> &rarr; <menuchoice>Workspace</menuchoice> or in <menuchoice>System Settings</menuchoice> &rarr; <menuchoice>Input Devices</menuchoice> &rarr; <menuchoice>Mouse section</menuchoice> for older versions of '''System Settings''')

To select and deselect files and folders hover mouse cursor above icon and click the emerging plus sign to select and minus sign to deselect. Like this:

[[Image:Dolphin folder hover.png|thumb|240px|center]]

When you click the plus-sign, this file or folder will be added to your selection. You can select multiple files in the same way. Selection can be done also by dragging a rectangle (sometimes called the "rubber band" method), and selection and deselection with <keycap>Ctrl + click</keycap> for one at a time and <keycap>Shift + click</keycap> for a consecutive range.

Many selected files looks like this:
[[Image:Dolphin folder hovered deselect.png|thumb|240px|center]]

'''Creating a new folder''': You can create a new folder in the active directory using <menuchoice>context (right-click) menu</menuchoice> &rarr; <menuchoice>Create new</menuchoice> or the <keycap>F10</keycap> shortcut.

''Tabs'': '''Dolphin''' supports tabbed browsing. A new tab can be opened for example from <menuchoice>File</menuchoice> &rarr; <menuchoice>New Tab</menuchoice> (if you have enabled menu bar), by <keycap>Ctrl + T</keycap> or by middle mouse click on folder icon and navigation buttons.

{{Note|Starting from KDE 4.7, Dolphin's menu bar is hidden, but easy to reach and restore. If you prefer menu bar to be present, you can enable it by selecting <menuchoice>Control</menuchoice> &rarr; <menuchoice>Show Menubar</menuchoice> or pressing <keycap>Ctrl + M</keycap>.}}

'''Dolphin''' opens by default when we click on any folder. It can also be started from [[Special:myLanguage/Plasma/Kickoff|Kickoff menu]].

== The Interface ==

=== Location Bar ===

'''Dolphin''' integrates a new concept to use the location bar in a faster and more precise way: therefore a breadcrumb location 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. In this way you can reach a parent folder from a sub folder in a very quick way.

Between the buttons which represent a folder there is a small arrow which is a button as well. By clicking this arrow you can see a list of all the subdirectories on the same level as your current one, giving you a quick directory change.

[[Image:Dolphin_nav.png|400px|thumb|center|Change directories quickly]]

There is also a classical location bar which displays the complete path. To use this style you can right click on the Location Bar and select <menuchoice>Show Full Path</menuchoice>. If you want the Location bar to become editable, trigger the keyboard shortcut <keycap>Ctrl + L</keycap> or select <menuchoice> Control</menuchoice> &rarr; <menuchoice>Location Bar</menuchoice> &rarr; <menuchoice>Editable Location </menuchoice>. By clicking on the free space next to the last displayed folder in the breadcrumb style you can switch to an editable Location Bar as well. If the editable style is selected a checkmark is displayed at the end of the location bar. This checkmark is a button which can be used to change back to the breadcrumb style. Of course menu and keyboard shortcut can be used, too.

=== Split View ===

'''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]], or [[Special:myLanguage/Krusader|Krusader]]. This is a very comfortable view to copy or move files from one folder to another.
[[Image:Dolphin split view.png|thumb|350px|center]]

You can split the view by clicking on <menuchoice>Split</menuchoice> in the tool bar or, if you have enabled menu bar, <menuchoice>View -> Split</menuchoice> (keyboard shortcut <keycap>F3</keycap>). To change back to only one folder view you can click on <menuchoice>Close</menuchoice> or just press <keycap>F3</keycap> again. 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. The active 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 location bar and each view can use a different view mode.

=== Sorting Files ===

By default, the files in the currently displayed folder are sorted in ascending alphabetical order. However, this can be changed by selecting <menuchoice>Control</menuchoice> &rarr; <menuchoice>Sort by</menuchoice>.

Files may be sorted by the following attributes

* Name
* Size
* Date
* Permissions
* Owner
* Group
* Type
* Link Destination
* Path

The sorting method can be changed by selecting <menuchoice>Sort by</menuchoice> from the toolbar and then select <menuchoice>A-Z</menuchoice> or <menuchoice>Z-A</menuchoice>. Additionally you may choose whether folders should be listed first by selecting <menuchoice>Folders First</menuchoice>.

=== View Mode ===

'''Dolphin''' features three different folder view modes:

* {{Icon|breeze-dolphin-view-icons}} '''Icons''' shows each file or folder as an icon with its name

* {{Icon|breeze-dolphin-view-compact}} '''Compact''' is the same as icons, but in a more compact form, allowing more folders and files to be displayed at once

* {{Icon|breeze-dolphin-view-details}} '''Details''' presents a list of files and folders, giving information on each, including but not limited to size and date

The mode can be changed from within Dolphin

* Select <menuchoice>View Mode</menuchoice> from the <menuchoice>View</menuchoice> menu. This option is only available if the main Menubar is enabled

* Select <menuchoice>View Mode</menuchoice> from the <menuchoice>Control</menuchoice> menu. This option is only available when the main Menubar is disabled

* By selecting the appropriate icon from the main toolbar, if it is enabled

* Using the default keyboard shortcuts:
** <keycap>Ctrl+1</keycap> switches to the Icon display mode,
** <keycap>Ctrl+2</keycap> switches to Compact and,
** <keycap>Ctrl+3</keycap> switches to Detailed view.

==== View as Icons ====

Each file and each folder is represented by an icon in this mode. Instead of displaying an icon a preview of the file can be shown. This feature can be turned on/off via the menu <menuchoice>View</menuchoice> &rarr; <menuchoice>Preview</menuchoice> (if menu bar is enabled) or via the main toolbar button <menuchoice>Preview</menuchoice>.

There is the possibility to display additional information below the icons. These can be turned on/off via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Additional Information</menuchoice> or <menuchoice>View</menuchoice> &rarr; <menuchoice>Additional Information</menuchoice> (if menu bar is enabled). 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 <menuchoice>Control</menuchoice> &rarr; <menuchoice>Show in Groups</menuchoice> or <menuchoice>View</menuchoice> &rarr; <menuchoice>Show in Groups</menuchoice> (if menu bar is enabled). 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 criteria.
[[Image:Dolphin show in groups effect.png|thumb|240px|center]]
=== Details ===

In view mode ''"Details"'' additional information is displayed by default in contrast to view mode ''"Icons"''. All files are listed in a tabular. The context menu of the table header offers the possibility to add additional columns. The following columns are available:

* Size
* Date
* Permissions
* Owner
* Group
* Type 
* Link Destination 
* Path
Column ''"Name''" is always displayed. By clicking on the header of one of the columns the table will be sorted by this column. By clicking on the same column header the sorting sequence is reversed.

It is possible to display the folders as a tree. In this mode a ''> symbol'' is shown next to the folder. By clicking on this sign the folder is expanded and all containing sub folders and files are also shown in the table but they are attenuated. By clicking the sign, which displays an ''arrow pointing downwards'', again the expansion is closed. Of course the tree structure can be used for as many folders as wished. In latest KDE releases, the tree view is enabled by default, but can be deactivated via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Configure Dolphin</menuchoice> &rarr; <menuchoice>View Modes</menuchoice> &rarr; <menuchoice>Details</menuchoice> with option <menuchoice>Expandable Folders</menuchoice>.

===Setting defaults for all folders===

Under <menuchoice>Control</menuchoice> &rarr; <menuchoice>Adjust View Properties</menuchoice> (or under the menu item <menuchoice>View</menuchoice> &rarr; <menuchoice>Adjust View Properties</menuchoice> if you have enabled menu bar) you can set any of these attributes to be the default for all folder views.

== Panels ==

'''Dolphin''' contains several panels, which can be activated via menu <menuchoice>Control</menuchoice> &rarr; <menuchoice>Panels</menuchoice>. Each panel can be placed in the left or right docking area. To move a panel you have to unlock panels (right clik on a panel and select <menuchoice>Unlock Panels</menuchoice>), click on the header and ''Drag&Drop'' the panel. The area where the panel will be placed on mouse released is highlighted. It is possible to stack panels on top of each other. In this case the panels are placed into tabs.

In the header of each panel there are two buttons. The button near to the caption undocks the panel. This makes the panel an independent window which "floats" above '''Dolphin'''. The window is still combined with '''Dolphin''' and cannot be displayed without '''Dolphin''' and cannot for example be minimized like normal windows. By clicking the button again the panel is docked again. The second button will close the panel.

=== Non Modal Dialogs ===

When Moving, Copying or Deleting files/directories the dialog disappears even when the operation has not yet completed. A progress bar then appears in the bottom right of the screen, this then disappears also, if you want see the progress you need to click a small (i) information icon in the system tray.

{{Warning|New users who are not used to this way of working (and even experienced users) can get caught out by this, if you are Moving, Copying or Deleting large directories then you need to use the icon to monitor the progress of your operation.
If you don't then any subsequent actions you do, may well use an incomplete file structure resulting in corrupted files.  '''You have been warned!'''}}

=== Places ===

'''Dolphin''' contains a new kind of bookmarks ''Places''. These are displayed in a panel which can be activated via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Panels</menuchoice> &rarr; <menuchoice>Places</menuchoice> (keyboard shortcut <keycap>F9</keycap>). The default Places are identical to the ones shown in the category ''Computer'' of the K-Menu [[Special:myLanguage/Plasma/Kickoff|Kickoff]].

By clicking one of these places it will be opened in the current folder view. The context menu offers the possibility to edit the places or to remove them again. It is also possible to hide entries temporarily.

The context menu of a folder can be used to add this folder an another entry to the ''Places'' panel. Therefore there is a menu item <menuchoice>Add to Places</menuchoice>. You can also Drag&Drop a folder to the Places panel.

The places panel also contains entries to connected removable devices like USB-keys or CDs. A small plug icon indicates if the device is mounted. The context menu offers the possibility to unmount the device.

The places are used as the basis in the breadcrumb navigation bar. Each address is shown in relation to the nearest parent folder which is one of the places.

=== Information ===

The information panel can be activated via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Panels</menuchoice> &rarr; <menuchoice>Information</menuchoice> (keyboard shortcut <keycap>F11</keycap>). This panel displays a preview or an icon of the currently selected file/folder or of the file/folder below the mouse cursor. Some additional information like change date or size to the file/folder is displayed as well.

The information panel offers the possibility to rate files, add a comment or tag a file. This is one of the interfaces to the semantic Desktop [[Special:myLanguage/Nepomuk|Nepomuk]] which provides the advantages of the semantic web for the desktop. Starting from KDE 4.2 it is possible to search for the semantic links given by the tags.

[[Image:dolphin_panel.png|thumb|240px|center|The Information Panel]]

{{Tip|1=If you are wondering about missing mp3 ID tags (title, time ...) with some files it is most likely that ID3 Version 2 tags are missing. You can add ID3 version 2 tags with '''KID3''' for example.}}

=== Folders ===

A panel providing a tree structure for the file system can be displayed via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Panels</menuchoice> &rarr; <menuchoice>Folders</menuchoice> (keyboard shortcut <keycap>F7</keycap>). The tree structure offers the possibility by clicking the > and  &darr; signs to expand/collapse sub folders. By clicking on one of the folders the content will be displayed in the current view.

=== Terminal ===

The terminal emulator [[Special:myLanguage/Konsole|Konsole]] can be displayed directly in '''Dolphin''' via <menuchoice>Control</menuchoice> &rarr; <menuchoice>Panels</menuchoice> &rarr; <menuchoice>Terminal</menuchoice> (keyboard shortcut <keycap>F4</keycap>). This makes it possible to use shell commands directly in '''Dolphin'''. The terminal is opened in the folder which is displayed in the current view. <keycap>Shift + F4</keycap> opens [[Special:myLanguage/Konsole|Konsole]] in new window.

[[Image:dolphin_terminal.png|thumb|240px|center|Dolphin with a Terminal]]

==Bookmarks and Places==

KDE Plasma offers two different systems of user-based links to different locations in the file system. One is called ''Places'' and the other one is called ''Bookmarks''. They reside in different files, and have different functions. This offers more flexibility, however, it makes it necessary to learn the differences.

[[Image:Konq3bookmarks.png|350px|thumb|center|KDE3 Konqueror didn't share bookmarks]]

In contrast to the way '''Konqueror''' stored the bookmarks back in KDE3, both ''Places'' and ''Bookmarks'' are available to all applications as well as the '''Dolphin''' file manager. More of that later.

=== Places in applications ===

====Places for system-wide navigation====

There is a default set of ''Places'' -
:Home
:Network
:Root
:Trash
but you can add other places.  In '''Dolphin''', right-click on a folder and select <menuchoice>Add to Places</menuchoice>, or just drag a folder onto Places.

[[Image:DolphinAdd.png|350px|thumb|center|Adding a bookmark to Places]]

By default this "Place" will be visible in all applications.  If you want to keep it constrained to '''Dolphin''', you need to right-click on the new name in the Places list, where you will find the option to Edit it.  There is a check-box for <menuchoice>Only show when using this application (Dolphin)</menuchoice>.

[[Image:OnlyShowIn.png|350px|thumb|center|This Place will only be visible in Dolphin]]

You can see the result of that command if you read {{Path|~/.local/share/apps/kfileplaces/bookmarks.xml}}.

In some applications too there is an option in the File menu to add a folder to Places.  At this stage, however, applications vary in which features are available.  The important thing to remember is that ''the default is for Places items to be available to all applications in the <menuchoice>File</menuchoice> &rarr; <menuchoice>Open</menuchoice> dialogue.  ''

====Constraining to one application====

Some applications allow you to edit items in the Places menu.  For instance, if in [[Special:myLanguage/Gwenview|Gwenview]] you right click on a folder in Places you can set an option to <menuchoice>Only show when using this application (Gwenview)</menuchoice>.

[[Image:OnlyShowIn2.png|350px|thumb|center|Constraining a bookmark to an application]]

If you need to constrain to an application that does not yet allow you to do that, the only way left is to edit the file ~/.local/share/kfile/bookmarks.xml.  Immediately before the </metadata> tag you will need to add the line {{Input|1= <OnlyInApp>appname</OnlyInApp>}}

===Bookmarks in applications===

====Enable bookmarks====

Bookmarks are not enabled in dialogs by default. To enable them
* Open the <menuchoice>File</menuchoice> menu and select <menuchoice>Open</menuchoice> or <menuchoice>Save</menuchoice>
* Click the '''Options''' {{icon|breeze-configure}} icon
* Select <menuchoice>Show Bookmarks</menuchoice>

[[Image:EnablingBookmarks.png|350px|thumb|center|Enabling Bookmarks]]

==== Using bookmarks ====

Bookmarks are the second class of user-based links to the file system. Remember opening <menuchoice>File</menuchoice> &rarr; <menuchoice>Open</menuchoice> and using the spanner/wrench?  Next to it is a yellow star.  This is the ''bookmark management menu''.

[[Image:BookmarkManagement.png|350px|thumb|center|Manage Application bookmarks here]]

Here you can define bookmarks that will be visible in the same menu on any application.  They are stored in one file, {{Path|~/.local/share/kfile/bookmarks.xml}}, which is used by all applications having that menu.
<span id="Archive Management in Dolphin"></span>
===Archive Management in Dolphin===

Managing archives now becomes simple.  In any directory in '''Dolphin''', highlight the files that you want to compress, and right-click.  Here, using the Compress option, you can elect to create a RAR archive, a Gzipped tar archive, or define another compression mode that you have already set up.

[[Image:Compress.png|350px|thumb|center|Create a new archive]]

Similarly, if you right-click on an existing archived file you get a range of actions added to the right-click menu.  You can extract the archive to the current folder, to an autodetected subfolder or to another place of your choosing.

Should you wish to add files to an existing archive, you can choose <menuchoice>Open with Ark</menuchoice>.

[[Image:ManageArchives.png|350px|thumb|center|Manage existing archives]]

==More Cool Actions==

===Change a File Association on-the-fly===

Have you ever wanted to open a file, only to find that it is [[Special:myLanguage/System_Settings/File_Associations|associated]] with an application that is not of your choice?

You can, for one, alter this in <menuchoice>Kickoff</menuchoice> &rarr; <menuchoice>Computer</menuchoice> &rarr; <menuchoice>System Settings</menuchoice> &rarr; <menuchoice>Common Appearance and Behavior</menuchoice> &rarr; <menuchoice>File Associations</menuchoice>.  This is the same as running   '''kcmshell5 filetypes''' in a Konsole.

Alternatively, if you want to change '''multiple''' associations right quick, you would edit the *.desktop file directly, e.g. the file {{Path|/usr/share/applications/org.gnome.Builder.desktop}}. For example, Gnome Builder associates with a great number of file-types which may not be desirable. So the line
    MimeType=application/javascript;   # we do not want all of these ....

may be shortened or commented out with # . Maybe a line 
 
    InitialPreference=2
    X-KDE-InitialPreference=3

in the builder.desktop file helps to keep your previous default associated app, with builder being only secondary or tertiary option.

Thirdly, '''Dolphin''' and '''Konqueror''' offer a quick method for changing a '''single''' association:
Right-click on the file and select <menuchoice>Properties</menuchoice>. The first line there is descriptive, something like:  {{Output|1=Type: XML document}}

At the same level, on the right, there is a spanner (wrench).  Click on that and you can add or change an association.

Similarly, by working on a folder, you can change the default file manager to/from '''Konqueror''', if you choose, or add another image browser to the possible associations.

===The Actions sub-menu===

The <menuchoice>Actions</menuchoice> sub-menu opens up a whole lot more cool things to do from '''Dolphin'''.  Some possibilities only appear when applicable to the file you have selected.  An apps .desktop file below {{Path|/usr/share/applications}} defines what actions are applicable for a particular type of file. Some of the options are
* Convert an image file to a different format
* Preview the file
* Download a remote file with [[Special:myLanguage/KGet|KGet]]
* Sign and/or encrypt the file, according to the encryption software installed

===Encode and copy audio CD tracks===

* Insert an audio CD
* Navigate to this CD in '''Dolphin''': it must appear as "Volume" in your '''Dolphin''' 'Places' or you can reach it by typing audiocd:/ in the address bar.

[[Image:Cdaudiodolphin.jpeg|550px|thumb|center|Dolphin presenting audio CD]]

You now notice that '''Dolphin''' is proposing a WAV file for each track, plus:
* a CDA folder containing indexing information in the usual CDA format.
* a Whole CD folder, containing one file for each format (.cda, .flac, .mp3, .ogg, .wav) holding all the tracks
* a FLAC folder, containing the tracks encoded into FLAC format (lossless information format)
* an Information folder containing the CDDB informations
* an MP3 folder, containing all the tracks in MP3 format
* a Ogg Vorbis folder, containing the tracks encoded in OGG format

You then just have to copy the folder of your choice, in your preferred format to obtain the relative encoded version of your CD!

=== Using <tt>timeline</tt> to have your recent files as startup folder ===

[[File:Recent.jpg|400px|thumb|right|Have your recent files always in Dolphin]]

You can start up dolphin (with '''baloo''' up and running) with a view of ''recently modified files'': Just navigate to the address/location of  <tt>timeline:/today/</tt> (copy paste it to the address bar) or use it as '''dolphin start-up-folder''' in dolphin-settings.
