Archive File Type Not Supported?

Hello,



This is what it keeps saying whenever I open to try and extract a .RAR file. I transfered all of them on my Macintosh OSX and Windows platform and they worked just fine, I don't know what's up with that. I've tried Ark and Archive Manager, same thing. Anyone have an idea what to do about that?

Thank you.

RAR support isn't included in Ubuntu by default (I think because it's patented). Just open up the package manager and install unrar
