DAA2ISO

DAA2ISO is a handy and reliable command-line utility aimed at converting single or multi-part DAA (Direct Access Archive) and GBI files to ISO format in just a few steps.
DAA is a proprietary file format for disk images developed by PowerISO. Although supported by gBurner, MagicISO and UltraISO, the format doesn’t make the list of other software applications belonging to the virtual image category such as Alcohol 120% and Daemon Tools.
Since ISO is a highly popular disk image format, it is supported by almost all software dedicated to reading and playing virtual images. However, the less known DAA format can be converted to ISO by means of the DAA2ISO utility.

Simple conversion mode

Usage is not rocket science. Suffice to say that there are only two steps you need to complete in order to achieve the conversion.
When you launch the EXE file, a command-prompt window displays a dialog requiring you to select the source file, then to choose a name for the output ISO. User efforts are minimized to completing just these two operations and nothing more.

Multi-part file support

What we found to be an interesting feature about this program is the fact that it supports multi-part files, but you don’t have to perform the conversion for each part. The application prompts you to select the first part and automatically retrieves the rest of them, provided that they are in the same folder.

Bottom line

In conclusion, DAA2ISO is the perfect solution for converting DAA / GBI images to a widely supported format, namely ISO. In addition, it’s extremely easy to use and portable, which means you can carry it on a removable drive and use it on any computer.
