I just switched to Fedora 22 and decided to go for Gnome3 this time instead of XFCE. I like the Thunar file manager so I downloaded it. I've had trouble setting it as the default file manager though.

What I tried:

I ran exo-preferred-applications. Under Utilities -> File Manager I selected Thunar.

The problem:

It's not acting as the default file manager. When I open my Downloads folder from my browser I still get Nautilus. Same when I click on my "Places".

In Fedora 25, the appropriate file is /usr/share/applications/gnome-mimeapps.list. Change the inode/directory entry to point to your file manager of choice. Change takes place immediately and the Places menu opens the newly selected application.


You could try editing /usr/share/applications/defaults.list and changing the line




or some order that suits your needs.

    Thanks for the help! Unfortunately there is not defaults.list in my /usr/share/applications. Is that normal?

    Every distro is different, but you can try finding it with $ locate defaults.list. May 30, 2015 at 20:48

    In Debian Jessie no such file is existing.
