Here you configure the basic operations. The page is divided into three tabs: General, Viewer/Editor, and Atomic extensions.


The following options determine basic aspects of operation:

  • Warn on exit: if checked, Krusader warns you every time when exit action is triggered.

  • Show and close to tray: If checked, the Krusader icon will appear in the system tray. When you minimize Krusader, it will not appear in the taskbar. It also will not exit if you close the main window. Instead you can quit Krusader by selecting FileQuit menu item or the context menu of the tray icon.

  • Use MIME type magic: MIME type magic is a mechanism which allows Krusader to inspect the files in the panels and determine their type even if the file has no identifying extension. For example, if you take an image file - image1.jpg - and rename it to image1, Krusader will still know it is an image file and work with it accordingly. However, this mode of operation is slower (while refreshing the panel, or changing folders), so try Krusader with and without MIME type magic and decide what is best for you.

  • Temp Folder: this option selects the base folder for Krusader's temporary files. The actual files will be created in separate folders under the 'Temp folder', so that each user running Krusader will have their own temporary subfolders under the chosen folder.


    You must choose a temporary folder to which all users running Krusader have full permissions!

Delete mode (Delete files/Move to trash): when Krusader deletes files it can either really delete them or move them to the trash folder, thereby making them available via Plasma™'s trash.

External Terminal: choose which terminal emulator will be used when Krusader opens a console window (via F9, or ToolsStart Terminal menu option).

Embedded Terminal sends Chdir on panel change: if unchecked, there will be no cd command sent to the Terminal Emulator if the panel folder changes.

Active panel follows Embedded Terminal working directory: if unchecked, active panel stays unchanged while the user navigates in the embedded terminal (using cd, popd, etc).

Toggle Fullscreen Embedded Terminal: if checked, Krusader shows fullscreen terminal in Midnight Commander style (Terminal is shown instead of Krusader window).


Here you can change the viewer and editor settings:

  • Internal editor and viewer opens each file in separate window: check this item if you want each file to be opened in a separate window. If unchecked, each file will be opened in a tab in the same Viewer/Editor window. Every tab in such a window can be closed, among other common methods, by clicking on the tab with the middle mouse button.

  • Hide the tab bar when only one tab is opened: check this item if you want the Viewer/Editor tab bar to be hidden if only one tab is open.

  • Default viewer mode:

    • Generic mode: use the systems default viewer.

    • Text mode: view the file in text-only mode.

    • Hex mode: view the file in hex-only mode.

    • Lister mode: Fast text/hexadecimal viewer for huge filesizes. Krusader lister never loads the whole file into memory, just a little part of it, and uses caching for faster scrolling. Remote files are downloaded, but during the download, viewing the downloaded part is possible. If a file constantly changes, then it can also be viewed, lister will always see its current state.

    • Use lister if the text file is bigger than: 10 MB (default value): checks whether a text file is bigger than 10 MB (configurable), and if yes, then Krusader Lister is used instead of Plasma™'s default viewer.

    • Use Okteta as Hex viewer: if checked (default option), use Plasma™ hex editor Okteta to view raw data. To use this option you should install Okteta package first.

  • Editor: choose what editor will be used when editing a file (via F4). Default the internal viewer is used, this is the Plasma™'s default viewer.

Atomic extensions

Atomic extensions: predefined atomic extensions like .tar.gz are shown as one part in the Ext Column of the List Panel.
