Reason: Expand on the KDE5 version (Discuss in Talk:Dolphin#File previews)

This article is about Dolphin, the default file manager of the K Desktop Environment. For the game emulator, see Dolphin emu.

## Installation

Install the dolphin package, or dolphinpart4 for the legacy KDE4 version.

For version control and Dropbox support, install dolphin-plugins. The Compare files dialog depends on kompare.

## Usage

### Open Terminal

Dolphin and other KDE applications use konsole by default. To change the default terminal emulator, run `kcmshell4 componentchooser` and select Terminal Emulator > Use a different terminal program.

### KIO Slaves

Dolphin uses KIO slaves for network access, trash and other functionality, unlike GTK+ file managers which use GVFS. Available protocols are shown in the location bar (editable mode) [1]. To quickly bookmark them, right-click in the workspace, and select "Add to Places".

## Troubleshooting

### No search results

If Baloo is enabled, Dolphin attempts to use it for file searches even if no file index is present. Either create a Baloo file index, or disable file indexing through `kcmshell4 kcm_baloofile`.

### Transparent fonts

Fonts in selection frames may become transparent when using the GTK+ Qt style. Native Qt styles such as Cleanlooks and Oxygen are unaffected.

### Unicode characters are not shown

This was a general issue in Qt4 and kdelibs, solved in v4.11 and later versions. [2]

### Crashes on mounted SMB share

See Samba#Unable to overwrite files.

### Cannot write to NTFS: Operation not permitted

This article or section is a candidate for merging with File manager functionality.

Notes: Not specific to dolphin (Discuss in Talk:Dolphin#)

If you are not able to do any write operations (create/delete/rename file/folder) as normal user to your NTFS partition, then you probably missing to install the ntfs-3g package. See NTFS-3G for details.
