I've recently came back to Ubuntu from Kubuntu, but I really like Dolphin. Is there any way how to set it up as default file manager?
Open a terminal, e.g. using Ctrl+Alt+T
exo-utilsby running the following command in the terminal:
sudo apt-get install exo-utils
Run the following command in the terminal:
In the window that opens, click on Utilities
On the File Manager section, click the drop-down menu arrow + Other...
Adjust to show all files and select
dolphin.desktop(wherever you find it)
To set Dolphin as default:
xdg-mime default kde4/dolphin.desktop inode/directory
To set Thunar as default:
xdg-mime default Thunar.desktop inode/directory
Run either on the terminal as regular user.
This link should help you to change the file manager. https://help.ubuntu.com/community/DefaultFileManager
Adding to Rucent88 answer:
For me the dolphin desktop file was stored in
xdg-mime default org.kde.dolphin.desktop inode/directory
did the trick.
Keep in mind to have a look where the desktop link is located. Have a look at the file list of your installed file manager to see how the desktop link is called if you can't find it.
also it works only with:
xdg-mime default dolphin.desktop inode/directory application/x-gnome-saved-search
