Change default for opening mounted volumes in Unity launcher

[TheCat]

I automount two NTFS volumes on login. These display in both the desktop and the Unity launcher.

The first time I clicked one of them in the Unity launcher, it asked if I wanted to use Nautilus or Thunar. I chose Thunar.

Now, when I open the volumes in the Unity launcher, it always uses Thunar. When I open the volumes on my desktop, it always uses Nautilus.

Is there any way to standardize these, so that I use either Thunar or Nautilus, but not both? And how do I switch back and forth? Where can I reset the Unity launcher to use Nautilus again?

Greetings.

I marked the only ones that may be related. Backup these settings, remove them, and relogin.

That doesn't seem to have had an effect.

Then restore the settings as they were.

Since I have no Natty install running, I can only guess now:

Check the settings in "dconf-editor", see this guide on how to install it, and more:

Did that already, no answers appear there.

So, in a backhanded fashion, I solved this by removing Thunar from my system. Clicking on a mounted volume in the Unity launcher after removing Thunar caused it to re-prompt me to ask which file manager I wanted to use, and I was able to choose Nautilus.
