1. Common questions

Q: What is Double Commander?

A: Double Commander is a cross-platform, twin-panel file manager. Details see here.


Q: What's new in this version?

A: History log can be found online at this page. But the project is now under development, so later nightly builds contain many new features and improvements.


Q: Is it a Total Commander® for Linux?

A: No, this is another program from other developers. It now supports Windows®, GNU/Linux operating systems with toolkits GTK2 and Qt and Mac OS.


Q: What is the difference between this program and my favorite file manager (Total Commander®)?

A: The goal of the project is to create a program close to TC in operation and with maximum compatibility via the plugins and configuration files. However, Double Commander has some important advantages: it's free to use, works with different operating systems, and is open source.


Q: I have a 64-bit Operating System. Can I download Double Commander for it?

A: Yes, builds for x64 exist under all supported platforms.


Q: How can I contact the developers of Double Commander?

A: Just write to the project's official forum and the developers will (possibly) pay attention to your suggestions.

2. Issues related to GNU/Linux

Q: Which version do I download?

A: If you have KDE - download a Qt-build; in other cases (Gnome, Xfce, LXDE) a build for GTK toolkit.


Q: Where is the project repository?

A: Repositories for GNU/Linux (CentOS, Debian, Fedora, openSUSE, Ubuntu):

release:

alpha ("nightly") build:

And you can download installation packages deb, rpm or "portable" (binaries packed with bz2) from the official site. Also you can download the source code and compile DC for yourself.


Q: Plugins from Total Commander® do not work!?

A: They work, but not all of them. Plugins from TC compiled for Windows® can only be used with Windows® version of Double Commander. But if the plugins have open source code, you can try to build them for GNU/Linux (or maybe ask the plugin developer to do it :)).

3. Interface configuration

Q: How can I change color settings for the panels?

A: To change the color, you must do the following:


Q: What are buttons R and All in the color settings?

A: They are as follows:


Q: Some text in a column overwrites another column's text!

A: Configurations → Options → Columns, set checkbox "Cut text to column width".


Q: How to associate my own icons with some file types?

A: You must do the following: Configurations → Options → File associations.


Q: How to create a splitter on the buttons panel?

A: Add a button from the category separator.

4. Issues related to control and navigation

Q: Is it possible to automatically move the cursor down one line after selecting using the Space key?

A: You must do the following: Configurations → Options → File views → When selecting file with spacebar, move down to next file (as with insert).


Q: Is there an ability to create a file operations queue?

A: A file operations queue was implemented in version 0.4.6 alpha, and will be added to the next stable release.


Q: Ctrl+A doesn't work, how to enable it?

A: You must do the following: Configurations → Options → Keys → Hot keys → In the category "Main", scroll to see command "cm_MarkMarkAll" and set Ctrl+A shortcut key for it.


Q: How to create my own context menu in this program?

A: Add button to the toolbar of the category "menu". See this section for an example.


Q: How to customize the context menu, for example, add the item "Open With"?

A: This can been incorporated into Double Commander; however, it's easy to add a command to the Actions item of the context menu. Here is an example of how to open any directory with root privileges:

  1. Under File Types, click Add, then enter, e.g. dir in the popup.
  2. Under Extensions, click Add, and enter, e.g. folder in the popup.
  3. Under Actions, click Add, then in the Action: edit line below, enter the action desired, e.g. Open as root
  4. In the Command edit line, enter the desired command: eg. gksu doublecmd %p
  5. After this just right click on any folder, choose Open as root and enter root's password. :)

5. Issues related to the built-in viewer (F3)

Q: Editor and browser windows appear in random positions, when Compiz is enabled.

A: Edit Compiz settings: place windows → windows with fixed positions and window rules → fixed size windows.

Code: (class=Doublecmd) & (title=/)

Q: Internal editor has a strange font — horizontal characters overwrite each other.

A: You must use monospace fonts in the viewer and editor.


Q: Viewer does not work with a few images, but works with most.

A: A component used to view the images did not support some JPG files.


Q: Viewer doesn't work with gif files?

A: Yes this is true, but it will be implemented soon.


Q: On some text files lines go beyond the window's edge.

A: Use "Show as Wrap text" option in Viewer.
