How do I fix Chrome 'show in folder' to open in file explorer and not in new tab?

Question

When I click "show in folder" Chrome opened the folder in a new tab. How can I fix this such that Chrome opens the folder with my standard file explorer (caja)?

Answer 1

I had the same problem after uninstalling pcmanfm and changing it for Thunar.

No need to install anything. Chromium/Chrome manages this function through xdg-open, and you have to modify it.

Check which is the default file manager in xdg-open:

$ xdg-mime query default inode/directory

It should give an unwanted one or one that is no longer installed.

Then set the desired default file manager in xdg-open. For caja it should be:

$ xdg-mime default caja.desktop inode/directory

or something really similar.
It worked immediately for me. I learnt it from: https://wiki.archlinux.org/index.php/xdg-open

Answer 2

Just execute the following lines and the problem will be fixed. No restart (neither of chrome, nor of anything else) is needed:

$ sudo apt-get install libfile-mimeinfo-perl
$ mimeopen -d /home/moose/Documents
Please choose a default application for files of type inode/directory

1) Caja  (caja-folder-handler)
2) Other...

use application #1
Opening "/home/moose/Documents" with Caja  (inode/directory)

Answer 3

For me, further to @elmanu's answer xdg-mime default caja.desktop inode/directory, it was running

update-desktop-database ~/.local/share/applications/

which finally updated the default application.

After this, running xdg-mime query default inode/directory now showed the new default application.
