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.

For version control and Dropbox support, install dolphin-plugins.

### Compare files

The Compare files dialog depends on kompare. Alternatively, you can compare files in any diff tool (such as meld) by selecting two files, right clicking, selecting open with, and then the diff tool.

### File previews

- kdegraphics-thumbnailers: Image files
- kdesdk-thumbnailers: Plugins for the thumbnailing system
- ffmpegthumbs: Video files (based on ffmpeg)
- raw-thumbnailer: `.raw` files
- taglib : Audio files
- kde-thumbnailer-apkAUR: Android application package files
- kde-thumbnailer-blenderAUR: Blender application files
- kde-thumbnailer-epubAUR: Electronic book files

## Usage

### Open Terminal

Dolphin and other KDE applications use konsole by default. To change the default terminal emulator, run `kcmshell5 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

### Device names shown as "X GiB Harddrive"

Create a filesystem label, or a partition label, and Dolphin will show this label in the device list instead of the size. See Persistent block device naming#by-label.

### 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.

### 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.
