how do you open DDA and UIF files?

Question

i downloaded one of each of thoes and i cant figure out hot to open them. all i see on the screen is a small incon that looks like a pice of paper with a symble in the center.

Answer 1

Those are proprietary disc image files, meaning that unlike ISO files these types can only be opened by the program that created them. I am assuming you meant DAA, which is PowerISO, and UIF is Magic ISO.

Answer 2

Those are disc image files. They can be burned to CD or DVD of appropriate type using appropriate burn programs, or they can be mounted by virtual drive programs.
