How to Open a DDA File

DAA files can contain the images of CDs and DVDs.

DAA, which stands for Direct Access Archive, is a file format used by an application called PowerISO. The DAA file format has the capability to store disc images, which makes it similar to the ISO file format. If you want to open a DAA file, you must first mount it onto a PowerISO virtual drive. After mounting the DAA file, you can open it just like you would open a physical CD or DVD.
