How to move files into /usr/bin in Nautilus without getting permission errors

I'm trying to move some files into /usr/bin in Nautilus but I'm getting permission errors. I know I can do it via the terminal using sudo but how can I do it in Nautilus? I would expect it to popup a box for me to enter my password like the admin screens in Ubuntu but it doesn't.

You can do it like this:

press Alt+F2 to open the 'Run Application' box
type gksudo nautilus in to the text box and press 'Enter'. This will prompt a password dialog box. Enter your sudo password and it will open nautilus with root privilege. From there you can move/copy files without any permission error.

Note: Just make sure that you don't delete/replace any system files.

I do this all the time, because I'm way to lazy to type I assume you might just want to keep it visual like me.

Applications--> Accessories-->Terminal

$ sudo nautilus
[sudo] password for me: my_password

the gui file manager will pop up running like root

Be mighty careful :-)

Root Nautilus script. This script opens Nautilus as root in the directory you select. how to install here
