I recently came across a new (to me) file extension. .daa
A google search told me that it is the "new" .rar and that I needed a program called "PowerISO" in order to burn an image of it to a dvd. I searched for any information on this in the Ubuntu community, but saw nothing.
Does anyone know anything about this? Where I could get PowerISO? Does it work? How is it different from the standard .rar?
