It's slightly frustrating (especially for new users), to discover that you can't always edit a file in the filesystem through the GUI because it requires admin privileges. I do most of my opening and editing through the Terminal but every once in awhile I just want a quick cut and paste. I started using this trick a few years ago and it works on all Debian based distros: Ubuntu, Mint, Etc. I originally found it at Boot and run Linux from a USB flash memory stick | USB Pen Drive Linux From Terminal, type Code: sudo su Enter your password Then enter: Code: gedit .gnome2/nautilus-scripts/Open\ as\ root A blank document will open. Enter the following 3 lines, click save and close the document: Code: for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do gksudo "gnome-open $uri" & done Type this into the terminal window: Code: sudo chmod +x .gnome2/nautilus-scripts/Open\ as\ root Next time you want to open a file as root, right click>scripts>Open As Root System restart may be necessary to get the right click.
