Double Commander: Less Known Features

I love Double Commander (DC) as a two-pane file manager and have already written about its basic features, how to add 7z support and some svn woes.

But DC has got some advanced features which you maybe wouldn’t expect.

  • Under Files-Multi Rename it has got a tool with which you can do a rule-based rename of many files easily. Very useful e.g. to rename songs downloaded from Amazon.
  • You can create symbolic and hard filesystem links. (Files-…)
  • Under Files-Compare by Content you’ll find a diff tool. But you could also configure DC to use the diff tool you prefer.
  • You can use DC as a FTP-client. When using this feature the first time, do this:
    1. Select Commands-Open VFS List.
    2. One of the panes then will show the entries FTP and Network.
    3. Double-click on FTP, then it will show Add connection and Quick connection.
    4. Double click one of them to add a connection.

DC is extremely configurable and extensible. Some examples.

  • The toolbar is fully configurable:
    1. Go to Configuration-Options-Toolbar.
    2. Click Insert new button.
    3. Select an internal command from the combobox or create an external command. You can use anything you want as a command and you can pass parameters like the currently selected file or path to it.
    4. Add a tooltip, icon and hotkey as you like.
  • You can connect file extensions with commands and hotkeys. For example, I as a software developer often need to know the version of a certain dll.
    So I connected the F3 key with a viewer for the dll version like this:

    1. Open Options dialog, select node File associations.
    2. Under File types select Add and add file type dll.
    3. Under Extensions select Add and type in dll.
    4. Under Actions select Add and then click the + and select View. This relates to the View command or cm_View in the DC.
    5. Under Commad select the + on the right and there Run in terminal (as my version reading program is a command line tool). Then select full path under the +. Resulting is a command like {!SHELL} version.exe %p

    Now, when a dll is highlighted and I hit F3, its complete version info is shown. Much easier and faster than right-click-properties-details.

  • You can color files according to their types: Configuration-Options-Colors-File types
  • All hotkeys are configurable: Configuration-Options-Keys-Hot keys

Epic Browser

Since some time, the video downloadhelper addon of Firefox did not work well for me. Now I’ve found the Epic Browser.

  • It is based on Chromium and fast.
  • It has got a working video downloader built in.
  • It’s got an adblocker built in.
  • It is dedicated to protect privacy as a number one concern.


Inkscape is a free, platform independent tool to work on vector graphics like svgs. Additionally it has got good commandline batch processing facilities which makes it the tool of choice for programmers.

See an example of how to crop or trim many svg files by commandline.

Inkscape and Eps

Inkscape on Windows cannot handle eps-files by default. To be able to handle eps-files, it needs Ghoststcript. A fine description of what is to do to install Ghostscript so that Inkscape can handle eps files.

To convert a lot of eps files to svg files at once, you can use tclkitsh and the following script:

set pathToInkscape "C:/Program Files/Inkscape/inkscape.exe"
set epsFiles [glob *.eps]

foreach f $epsFiles {
    set fbasename [file rootname [file tail $f]]
    if ![file exists $fbasename.svg] {
        puts  "$pathToInkscape  $f --export-plain-svg=$fbasename.svg"
        exec  $pathToInkscape $f --export-plain-svg=$fbasename.svg

1. Save the script as EpsToSvg.tcl.
2. Open the script in an editor and adapt the pathToInkscape. Save.
3. Open a command shell and cd to the directory where your eps files are located.
4. Then run tclkitsh EpsToSvg.tcl.
