Template:I18n/Language Navigation Bar

General information

Dolphin is the file manager of KDE.

I'll show how to use dolphin for common file managing tasks, and how to customize it to your needs.

Dolphin default.png

When we open the dolphin from Kickoff menu it shows starting directory - by default it is your Home directory.

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:

Dolphin folder hovered.png

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).

Many selected files looks like this:

Dolphin folder hovered deselect.png

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.


Kde3-button.png 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 This fork is not supported by KDE and is no longer maintained by its author.


Kde4-button.png In KDE 4 Dolphin opens by default, when we click on any folder, it can also be started from Kickoff menu.

Navigation Bar

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.

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.

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.

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 Midnight Commander. This is a very comfortable view to copy or move files from one folder to another.

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

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.

Icons

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.

Details

In view mode "Details" additional information are 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

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 reverted.

Since KDE 4.1 it is possible to display the folders as a tree. In this mode a plus sign 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 itenuated. By clicking the sign, which display a minus now, again the expansion is closed again. Of course the tree structure can be used for as many folders as wished. The tree view is disabled by default, but can be activated via "Settings -> Configure Dolphin -> View Modes -> Details" with option "Expandable Folders".

Columns

View mode "Columns" is inspired by the file manager Finder of Mac OS X. Entering a sub folder does not replace the current folder view but the content of the sub folder is listed in an additional column next to the column of the parent folder. This can be used for several hierarchies, so that you can navigate in an easy and fast way in the file system.

Panels

Dolphin contains several panels, which can be activated via menu "View -> Panels". Each panel can be placed in the left or right docking area. To move a panel you have to 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 withoud 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.

Places

Dolphin contains a kind of bookmarks which are called "Places". These are displayed in a panel which can be activated via "View -> Panels -> Places" (keyboard shortcut F9). The Places are identical to the one shown in the categorie "System" of the K-Menü 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 "Add to Places". 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 "View -> Panels -> Information" (keyboard shortcut F11). 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 are 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 Nepomuk which provides the advantages of the semantic web for the desktop. Starting with KDE 4.2 it will be possible to search for the semantic links given by the tags. Currently tagging only offers an outlook to future versions.

Folders

A panel providing a tree structure for the file system can be displayed via "View -> Panels -> Folders" (keyboard shortcut F7). The tree structur offers the possibility by clicking the + and - signs to expand/collaps sub folders. By clicking on one of the folders the content will be displayed in the current view.

Terminal

The terminal emulator Konsole can be displayed directly in Dolphin via "View -> Panels -> Terminal" (keyboard shortcut F4). So it is possible to use shell commands directly in Dolphin. The terminal is opened in the folder which is displayed in the current view.
