UPDATE: UIF (Universal Image Format) is another one of MagicISO’s proprietary image formats that no other software recognizes. You can easily convert these to standard ISO with Luigi Auriemma’s ‘UIF to ISO converter’!
.DAA is a proprietary image file format developed by PowerISO. It’s not free and is often used within filesharing communities to compress CD/DVD images. While it’s great for reducing file sizes, its exclusivity to PowerISO makes it horribly inaccessible. Wouldn’t it be handier to have it in the ubiquitous ISO-format instead? PowerISO provides a free converter for the Linux and Mac terminal, but it requires Windows users to buy the full version. Conversion of files works in the trial-version, though is limited to a maximm filesize of 300MB — a pathetic limitation, since CD images are generally larger than 600 Megs.
Luigi Auriemma has created a handy command line tool that converts .DAA to .ISO, which can be burned with any burner and mounted with free software like Daemon Tools. The latest version also includes easy-to-use dialog boxes for selecting source and destination paths.
