.DAA File

File extension daa is most like best known for it use for a CD/DVD disk image format, which supports some advanced features, such as compression, password protection, and splitting to multiple volumes (similar to .RAR and other compression formats).

Direct Access Archive, or daa file, is a proprietary file format for disk image files which supports advanced features such as compression, password protection, and splitting to multiple volumes.

It can be handled directly just like other formats, such as an ISO image and BIN, but is currently only usable by PowerISO software. Popular disk image mounting programs such as Alcohol 120% and DAEMON Tools currently do not support the mounting of DAA images.

Advantages of DAA file format:

• Can be mounted directly like an ISO or BIN file
• Allows for compression saving space and making it easier to download
• Can be password protected
• Can be split into multiple smaller files

Disadvantages of DAA file format:

• Can only be mounted with PowerISO (Windows only)
• As a proprietary format, it cannot be read by any free application (e.g. AcetoneISO uses PowerISO binary-only application to achieve conversion of DAA)

Files with daa extension are disk images in a proprietary format used by PowerISO similar to ISO format. DAA images can only be accessed with PowerISO, no other programs support them. They can be however converted to common ISO files with the DAA2ISO utility.
