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? -- Guy Fawkes, the only man to enter the house's of Parliament with honest intentions, (he was going to blow them up!)
