The default ubuntu distro can’t open .rar archives. To be able to open .rar files, you need to install the unrar application. To do this, enable multiverse repository (this is enabled by defaut) and go to the terminal. Type this code:
sudo apt-get install unrar
Done! You can now open your .rar files using the GUI like as you do in windows, or you can use the terminal with this code:
unrar x [filename.rar]
replace filename.rar with he name of your rar archive. (x is a shortcut for extract)
