External Hard Drive opens with Puddletag and not Nautilus

I’ve had this problem in the past and it’s just resurfaced on moving distro. I’m not sure what causes it, but the fact it’s happened more than once with Puddletag might suggest something’s wrong there.

My solution comes from instructions about how to change from Nautilus to Nemo, since that involves changing the program that handles certain MIME types.

Use this command in a terminal.

Nautilus

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

Nemo

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

I had a similar problem, when plugging in an external drive, Thunar was getting opened but I wanted Nautilus. I went to Thunar's preferences and disabled "volume management", not totally a solution but close to, at least Thunar doesn't automatically open now

You may need to check the system-wide default.list files that control default applications to confirm they have this line:

inode/directory=nautilus.desktop

Instead of "something else" to handle opening directories. From what I can tell (I am on Linux Mint 13) the files that you may need to check are:

/etc/gnome/defaults.list

/etc/gnome/defaults.list.dpkg-old

/usr/share/applications/defaults.list

/usr/share/gnome/applications/defaults.list

/usr/share/linuxmint/common/artwork/mime/defaults.list

I have noticed if I only change /etc/gnome/defaults.list or /usr/share/applications/defaults.list that the change is not permanent and will be reset after reboot.

I needed to modify these to use nemo.desktop instead of nautilus.desktop (in Mint I have purged nautilus as I use nemo as the file manager). When these files referenced nautilus.desktop (although nautilus was removed), I also had puddletag being called to open a folder!

When you plug-in your HD and when it prompts to choose an application: Choose "Nautilus "

or

Right click on folder -> Properties -> Open with -> choose "Nautilus"

or

Right click on folder -> Open with directly -> Other application -> Choose "Files/Nautilus" -> Remember this application
