i have recently installed a new file manager KRUSADER in my system (korora OS) . how to make it the default file manager instead of my current file manager Nautilus ...?

i tried to use :

xdg-mime default krusader.desktop inode/directory

but it reports an error :

/usr/bin/xdg-mime: line 820: /home/arghya/.local/share/applications/mimeapps.list.new: No such file or directory

should i create the folder 'applications'' and file mimeapps.list ..?

if so what entries should i put in it..? or is there any other way to make krusader the default file handler..?
