Pantheon Files is one of the many file managers available for Ubuntu. These file managers offer features that are not present in the default Nautilus file manager. One of the features I like in Pantheon Files is its Column View, where it allows navigation using Miller columns. This is similar to the column navigation in the Finder application on the Mac.
$ sudo add-apt-repository ppa:elementary-os/daily $ sudo apt-get update $ sudo apt install pantheon-files
To launch Pantheon Files, type Files in the Ubuntu Launcher.
Tried with: Pantheon Files 0.1 and Ubuntu 12.04 LTS
