'''Direct Access Archive''', or '''DAA''', is a proprietary file format developed by [[PowerISO Computing, Inc]] for [[disk image]] files. The format supports features such as compression, password protection, and splitting to multiple volumes. Popular Windows disk image [[Mount (computing)|mounting]] programs such as [[Alcohol 120%]] and [[Daemon Tools]] currently do not support the mounting of DAA images; Linux and BSD also do not support mounting images of this kind.<br />
<br />
Currently there is no published information about the format. Among mainstream applications, it can be opened or converted with [[MagicISO]] and [[UltraISO]]. Various free and open-source packages are also available to convert DAA to ISO images.<br />
<br />
==File Structure==<br />
Although lacking official documentation, DAA image files are [[zlib]]- or [[lzma]]-compressed [[ISO image]]s chunk by chunk.<ref>Text file in daa2iso: http://aluigi.altervista.org/mytoolz.htm#daa2iso</ref><br />
<br />
== Conversion ==<br />
''PowerISO'' provides free command-line tools for [[Linux]] and [[Mac OS X]] which allow the user to extract DAA files or convert them into [[International Organization for Standardization|ISO]] format, however these tools have not been updated to support the newest version of the DAA format. The PowerISO [[Microsoft Windows|Windows]] trial version only supports converting images from DAA files up to 300MB,<ref>{{Cite web |url=http://www.poweriso.com/faq.htm |title=PowerISO - Create, Edit, Extract, Mount, Compress, Encrypt, Split ISO file, ISO/BIN converter, Virtual Drive, DAA |access-date=2008-04-18 |archive-url=https://web.archive.org/web/20080512001322/http://www.poweriso.com/faq.htm |archive-date=2008-05-12 |url-status=dead }}</ref> less than half of the capacity of a standard [[CD]].<br />
<br />
''[[AcetoneISO]]'' is a free CD/DVD management application for Linux that can convert DAA to ISO with the help of the external PowerISO command-line tool for Linux.<br />
<br />
''daa2iso''<ref>[http://aluigi.altervista.org/mytoolz.htm#daa2iso daa2iso application for Windows]</ref> is an open source [[command line]] application has been developed to convert DAA files to ISO files. The program comes with a Windows binary and source code which compiles under Unix-like operating systems. daa2iso allows users to select the .daa file, and the location for the .iso output via standard windows open and save dialogs<br />
<br />
For Mac OS X, ''DAA Converter''<ref>[http://www.twilightedge.com/mac/daaconverter/ DAA Converter for Mac OS X]</ref> is a GUI application which wraps the daa2iso command-line tool (GNU license).<br />
<br />
==Features==<br />
Due to using freely available compression algorithms, DAA includes the following features that are absent in ISO (but can be obtained by manually compressing ISO files):<br />
*Ability to compress images, thus saving space and allowing smaller downloads<br />
*Can be password protected<br />
*Can be split into multiple smaller files<br />
