Program to handle .daa files?

[John Bowden <j-alan btconnect com>]

Hi folks
	I have just finished down loading some books for a friends son to help him 
with his maths. They have arrived in .daa file, which is a compressed iso 
type of file. You get a .daa file and a .nfo file. Any ideas as to what 
program will burn them or convert them to a burnning format that K3b will 
handle?
