After download a CD/DVD image file in DAA or UIF format instead of the popular ISO, it's a headache to find a converter to open such image file, or retrieve some files from the image. I have tried daa2iso, MagicISO, and Active@ISO Burner but found various problems.
PowerISO can convert CD/DVD image file formats from BIN, NRG, CDI, DAA, and UIF, etc. to ISO format, extract files from the image to the hard disk, and make image file in ISO, BIN, or DAA formats.
