I installed Ubuntu 12.10, then installed Nemo.

Now I would make Nemo the default file manager. I've search the web for a solution but everytime I restart my computer Nautilus come back.

Does anyone know an effective solution?

There is a much better way to do this without moving files and setting links. Just open a terminal with CTRL+ALT+T and than perform this command:

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

Than set up Nemo to handle your desktop:

gsettings set org.gnome.desktop.background show-desktop-icons false
gsettings set org.nemo.desktop show-desktop-icons true

I found that this method doesn't set nemo as the default file manager when, for example, opening an external hard drive from the launcher. I used the other answer and it worked like a charm. – Oct 24 '13 at 15:37 I do not use Unity, so can't test that. –  user5950 Oct 27 '13 at 20:16
In my case with 12.04 LTS the other answer worked well, this one was still launching nautilus as file manager –  danijelc Nov 9 '13 at 15:47

Open your terminal with CTRL+ALT+T and then paste this:

 sudo mv /usr/bin/nautilus /usr/bin/nautilus.back && sudo ln -s /usr/bin/nemo /usr/bin/nautilus

then try again, hope that helps.

Note that this will effectively make Nautilus inaccessible on your system unless you modify shortcuts to point to nautilus.back.

this is a hack, yet very effective! :) –  ihsan Apr 7 at 5:44
@Raja, This is a great answer. It's the only one that I find that will work. Hopefully eventually setting your default file browser will become a workable feature as with setting the default web browser. With this resolution, if you have an occasion to want to call Nautilus you can call it with nautilus.back. –  L. D. James Jun 27 at 14:05
