The GNOME developers removed it.
Other things removed ...
- Compact View
- ‘Type Ahead Find’
- ‘New file’ templates
- Application Menu
- ‘Go’ menu
- F3 split screen
- ‘tree’ view
- Bookmark menu items
- Backspace shortcut to return to parent folder
The only method I know to get it back is to uninstall Nautilus 3.6, remove the ppa and install Nautilus 3.4 from the default Ubuntu 12.10 repositories. Or start searching for another file manager. Have a look at: http://www.junauza.com/2012/07/best-alternative-file-managers-for.html
Keep an eye out for SolusOS Patched Nautilus. See feature 1 in the list below.
Warning: This is only for those who are using the official Nautilus 3.6 packages from the Ubuntu 13.04 (or 12.10 and 12.04) repositories.
If you want these features back in Ubuntu 13.04, a proper appmenu for Nautilus along with other features / options such as:
- customizable toolbar with back / forward buttons on the left: you can add or remove the up, refresh, home, computer and search icons and you can also add the old location / path bar toggle button which was removed from Nautilus starting with version 2.30;
- unified toolbar that spreads across the whole window width unlike in the original Nautilus 3.4 (also, only one toolbar is used when using the extra pane (F3) feature);
- other minor features like displaying the icons in the pathbar for Documents, Downloads, etc.
sudo add-apt-repository ppa:webupd8team/experiments
sudo apt-get update
sudo apt-get dist-upgrade
Revert to original Nautilus:
sudo apt-get install ppa-purge
sudo ppa-purge ppa:webupd8team/experiments
