How do I make krusader the default file manager?
1) Make a folder in your home directory called bin
mkdir ~/bin
2) Make a script called Nautilus that executes Dolphin and put it in this folder
gedit ~/bin/nautilus
3) Then copy this code into it and save
#!/bin/bash
exec krusader $@
exit 0
This will launch krusader
every time nautilus
was to be launched.
open your terminal with CTRL+ALT+T and paste this line
sudo mv /usr/bin/nautilus /usr/bin/natilus.back && sudo ln -s /usr/bin/krusader /usr/bin/nautilus
