一般信息

Dolphin 或是 Konqueror?

這份指南描述的是 KDE 4的 Dolphin。Konqueror是KDE 2和KDE 3預設的檔案管理員。你依然可以在KDE SC 4中使用Konqueror當預設檔案管理員。在KDE SC 4.2 以後，打開系統設定，然後找到預設應用程式，選擇Konqueror 或其他程式當預設檔案管理員。

介紹 Dolphin

Dolphin  是 KDE SC 的檔案管理員。

我會展示如何用 Dolphin 完成一般的檔案管理任務和自定它滿足你的需要。

當我們從Kickoff 選單裡打開 Dolphin，他首先顯示的是開始目錄-通常是家目錄 。

在檔案夾裡點一下即可打開檔案。你不必用雙擊。（如果你喜歡雙擊打開，KDE 4.5 中在 系統設定 > 硬體 > 輸入裝置 > 滑鼠部分 里改）。

要選擇和取消選擇檔案/資料夾，懸停滑鼠指針到圖示上，點擊出現的+號來選擇，點-號來取消選擇。像是這樣:

當你點擊+號，檔案/資料夾就會被選中。你可以用這種方法輕易選擇多個檔案（鼠標拖拽矩形選擇檔案也是有效的）。你也可以用Ctrl + 單擊一次一個的選定/取消選定，用Shift + 單擊來連續操作。

多個被選中的文件看起來是這樣的：

新增資料夾:你可以在當前活動的目錄下用滑鼠右鍵菜單新增資料夾，或快捷鍵F10。

分頁：Dolphin支援分頁瀏覽。舉例來說 檔案->新增分頁 或滑鼠中鍵點擊資料夾圖示和導航按鈕（前進/後退）。

預設點擊任何檔案夾都會啟動 Dolphin。也能在Kickoff 選單裡啟動它。

導航欄

Dolphin 整合了新概念以一種更快速和更準確的方法使用導航欄。因此使用了新的麵包屑（breadcrumb）導航欄。取代傳統的顯示完整的路徑，僅從「地址」之一開始的導航點作為按鈕顯示。點擊那些按鈕你能直接進入這個檔夾。所以你能快速的從一個子檔夾到達父檔夾。

在代表檔夾的按鈕之間有一個小的箭頭也是個可點擊的按鈕。點擊這個箭頭你能看到一份列表，列表裏是跟你現在這個目錄同級的所有子目錄（譯者注：這說的是你點當前這個檔夾按鈕前的「箭頭」的情況，其實列表顯示的就是「箭頭」前那個檔夾的所有子檔夾），使你能快速改變目錄。

快速改變目錄

同樣也有一個顯示完整路徑的經典導航欄。要使用這種樣式，你需要選擇查看 -> 導航欄 -> 顯示完整路徑或用鍵盤快捷鍵 Ctrl+L 觸發。點擊「麵包屑樣式」裏緊跟最後一個顯示檔夾的空曠區域，你也能改變到經典樣式。一旦選擇了「經典樣式」，一個標記符號就會在導航欄末端出現。這個標記符號是個按鈕，可以用來返回樣式到「麵包屑樣式」。當然也能用菜單和鍵盤快捷鍵。

拆分視圖

Dolphin 能夠拆分當前檔夾視圖產生出兩個彼此相鄰的檔夾視圖，參考Midnight Commander。這種流覽方式非常適合從一個檔夾複製或移動檔到另一個檔夾。

你能用查看 -> 拆分 (鍵盤快捷鍵F3)拆分視圖。要變回到只有一個檔夾視圖，你可以點查看 -> 關閉。小圖示會顯示哪個視圖會被關閉。取決於當前啟動的視圖，減號會顯示在圖示的左側或右側。啟動的視圖會被關閉。如果你想用鍵盤快捷鍵操作的話，需要知道這點。在工具欄上也有一個用來拆分和關閉視圖按鈕。這個按鈕也會顯示減號，所以很容易的能看出來哪個視圖會被關閉。

當然每個視圖都有他自己的導航欄，每個視圖也能用不同的視圖模式。

View mode

Dolphin 支持三種不同的視圖模式："圖示", "細節" 和 "分列"。可以通過菜單查看 -> 視圖模式變更或通過鍵盤快捷鍵Ctrl+1(圖示), Ctrl+2 (細節) 和 Ctrl+3 （分列）。在工具欄上也有對應每個視圖模式的按鈕，檔夾流覽的相關右鍵菜單也提供子菜單視圖模式來改變視圖模式。

圖示

在"圖示"視圖模式下每個檔和每個檔夾都用一個圖示表示。也可以顯示檔的縮略圖取代顯示圖示。這種做法可以通過菜單查看 -> 預覽或是通過工具欄按鈕開啟/關閉。檔預覽是有大小限制。這個大小限制可以在設置 -> 配置 Dolphin -> 常規選項預覽 -> 最大檔大小自定義。這裏也有選項在預覽時使用嵌入到檔裏的縮略圖（比如說mp3檔裏的專輯封面）。KDE 4.5中預覽通過設置-> 配置Dolphin -> 常規 -> 預覽選項開啟、配置。

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
• Link Destination
• Path

Additionally the sorting sequence can be defined by View -> Sort by -> Descending or View -> Sort by -> Folders First.

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 criteria.

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.

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 attenuated. 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.

Setting defaults for all folders

Under the menu item View -> Adjust View Properties 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 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 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 View -> Panels -> Places (keyboard shortcut F9). The default Places are identical to the one shown in the category System of the K-Menu 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 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 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.

The Information Panel

Tip

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 View -> Panels -> Folders (keyboard shortcut F7). The tree structure offers the possibility by clicking the + and - 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 Konsole can be displayed directly in Dolphin via View -> Panels -> Terminal (keyboard shortcut F4). 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. Shift + F4 opens Konsole in new window.

Road to KDE 4: Dolphin and Konqueror

Ars Technica: A First Look at Dolphin

Youtube - KDE 4 rev 680445 - Dolphin

Introducing KDE 4 Blog - Dolphin

Bookmarks and Places

In KDE3 you could create bookmarks in Konqueror, but they were not available to any other application. KDE SC 4.x opens up a great deal more flexibility - but that inevitably means more complication. In fact KDE SC 4 has three classes of Bookmarks, which need to be differentiated. They reside in different files, and have different functions.

KDE3 Konqueror didn't share bookmarks

Three kinds of bookmark

First, there is the set of bookmarks available only to Konqueror - web bookmarks. These are stored in ~/.kde/share/apps/konqueror/bookmarks.xml. Then there is a set which Dolphin calls Places. This set is available to all applications as well as the Dolphin file manager. Every time you use File -> Open you will see this set. The third set of bookmarks are Application Bookmarks. These share one file, regardless of the application that set them, and are available to all applications, unless you restrain them to a specific application. More of that later.

Enable bookmarks

In most distros Bookmarks are not enabled by default. In order to use bookmarks we first have to enable them. Open a File -> Open in most KDE applications and you will see, at the right-hand edge of the icon panel, a spanner or wrench. From the drop-down list, choose Show Bookmarks.

Enabling Bookmarks

"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 Add to Places, or just drag a folder onto Places.

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 Only show when using this application (Dolphin).

This Place will only be visible in Dolphin

You can see the result of that command if you read ~/.kde4/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 File -> Open dialogue.

Bookmarks in applications

This is the second class of bookmarks. Remember opening File -> Open and using the spanner/wrench? Next to it is a yellow star. This is the bookmark management menu.

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, ~/.kde4/share/apps/kfile/bookmarks.xml, which is used by all applications having that menu.

Constraining to one application

Some applications allow you to edit items in the Places menu. For instance, if in Gwenview you right click on a folder in Places you can set an option to Only show when using this application (Gwenview).

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 ~/.kde/share/apps/kfile/bookmarks.xml. Immediately before the </metadata> tag you will need to add the line

<OnlyInApp>appname</OnlyInApp>

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.

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 Open with Ark.

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 associated with an application that is not of your choice? You can, of course, alter this in System Settings -> Advanced -> File Associations. But Dolphin and Konqueror offer you a quick and cool method for changing a single association.

Right-click on the file and select Properties. The first line there is descriptive, something like:

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 Actions 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. Some of the options are

• Convert an image file to a different format
• Preview the file
• Download a remote file with 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.

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!

Have your recent files as home

Have your recent files always in Dolphin

Dolphin has access to a large number of file transfer protocols (KIO Slaves). One of those is provided by the KDE semantic search system (Nepomuk). Nepomuk offers a transfer protocol named history. You can navigate to it by entering timeline:/ in the location bar.

One particularly neat thing there is the ability to have the Today folder from the timeline:/ protocol in the Places sidebar (you can just drag it there!). You can then change the name and icon (do a right click on the new Today entry and choose Edit entry Today...).

It could be very useful to have this view of recently used files immediately when you start Dolphin. Unfortunately, as of Dolphin 2.1 (part of KDE SC 4.9) this is not possible without editing the Dolphin configuration file. See this blog for more details on that.

To edit the configuration file, first close all Dolphin windows. Dolphin will save its configuration upon closing, overwriting any changes you might make!

Then use KRunner (Alt + F2) to edit ~/.kde4/share/config/dolphinrc (or ~/.kde/share/config/dolphinrc, depending on your distribution) with KWrite as follows: kwrite ~/.kde4/share/config/dolphinrc. You can of course use any other editor as well, like Kate. In the configuration file, locate the [General] section to edit the HomeUrl into: HomeUrl=timeline:/today and save the file. You should now have the today view as default and have the files you're most often looking for at your fingertips!
