RAR not Roar

Want to open RAR files using Ubuntu ? Got files over 4 GB ? If so, make
sure you install the non-free version of RAR via Synaptic Package Manager.

Initially, I installed the free version ( unrar-free 1:0.0.1 ) but got
the following error message: -

unrar-free: invalid archive 'RenovationsSoftv1.rar': Value too large for
defined data type

when I attempted to extract files from a 6.8 GB archive.

Once I installed, and used, the non-free version ( unrar 1:3.8.2.1 ),
all was well.
