# Frequently Asked Questions (FAQ)

## 1. Common questions

Q: What is Double Commander?

A: Double Commander is a cross-platform file manager with two panels. 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® and GNU/Linux operating systems with toolkits GTK2 and Qt. In the future it will quite possibly support other operating systems like 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 both 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: There is no repository yet. But 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:

- Configurations → Options → Colors (but first you must create your own columns style)

- Configurations → Options → Columns, set default style, click "Edit" and configure :)

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

A: It's simply:

- `R` — restore color to the default.

- `All` — apply selected color to all columns.

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

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

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

A: You can edit the configuration file `doublecmd.ext`. For example, to associate an icon with image file types:

    [jpeg|jpg|gif|png]
    Name=images
    Icon=/home/rust/progs/doublecmd/pixmaps/32x32/mimetypes/image.png
    open=gthumb '%p'

In this case, all of the above extensions will be displayed with `image.png`.

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

A: To get the splitter, you need to specify "-" as a hint.

## 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: Set the key

    SpaceMovesDown = 1

in the [Configuration] section of the file `doublecmd.ini`. Or just enable it in the Options.

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: How to enable:

- Configurations → Options → Hot keys, set key for internal command `cm_MarkMarkAll`

- Add these strings to file `shortcuts.ini`:

      [Ctrl+A]
      Command0=cm_MarkMarkAll
      Object0=frmMain
      Form0=frmMain

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

A: Add button to the toolbar, choose `cm_ShowButtonMenu` as a command, and also add path to the *. bar file to the parameters.

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

A: This can be done via file association manually, associate programs with specified file types and also set default program.

"Configuration" — "File associations" — "File types" (enter any name here, e.g. media) — "Extensions" (add, e.g. avi) — "Actions" — click button "Add" (type open — "Command" type, e.g. totem-xine "%p" or mplayer "%p" or smplayer "%p" etc ... ). After doing this when you right-click on the file you can choose what to open.

By the way, it's easy to open any directory with root privileges, e.g. with Nautilus. You can add a new type to the "File associations" (e.g. dir), set folder as extension, set Open as root as action and type command: gksu nautilus "%p". After this just right click on any folder, choose Open as root and enter 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.
