I am currently using ubuntu 16.04. When I am using applications, such as Kile, to open documents I have to use ubuntu's default file manager. Right now I have Krusader installed(my choice of file manager).

How can I make it so that all applications (including Kile) use Krusader to open files?


Well Open terminal and install exo-utils

sudo apt-get install exo-utils

Now run the following command in terminal


Under Utilies Tab you will have File Manager to choose.

If you are using Xubuntu distros then go to
Settings Manager > Preferred Applications > Utilities , there you have the dropdown option to select the File Managers you already installed.

if above things fails then try running following command in a new terminal.

xdg-mime default Krusader.desktop inode/directory application/x-gnome-saved-search

  • Thanks for the quick response. However, I tried this solution and it did not work. When I click on the tabs in the Preferred Application window I get this error "(exo-helper-1:20840): Gdk-CRITICAL **: IA__gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed" . Also tried the las line and nothing happen. – dowewas Aug 25 '16 at 21:59
