Qu'est-ce qu'un fichier DAO ?
A DAO file is a disk image that contains a copy of the content stored on a CD or DVD. It is used to write the content it contains to recordable CDs or DVDs, to create duplicate or backup copies. Various CD and DVD duplication and burning software can create and use DAO files.
Plus d'informations
Disk-at-once, or DAO, is a method of writing data to a CD-R or DVD-R. While other CD and DVD writing methods write only portions of data (often, individual audio tracks) at once, DAO writes all data to a disc at the same time. This allows the person creating the disc to control whether there are gaps in the disc's data and, if so, what data those gaps contain. For example, using the DAO method, users can insert a "secret" audio track at the start of another track, or they can link tracks together with no audio gap at all.
Several CD and DVD authoring programs that can write discs using the DAO method save disk images as DAO files, and can load them as well. The data these disk images contain is used to produce duplicate DAO CD-Rs or DVD-Rs, which contain the same content as the DAO file.
Comment ouvrir un fichier DAO
You can open a DAO file with Smart Projects IsoBuster (Windows) or EZB Systems UltraISO (Windows), to view the data it contains. UltraISO also allows you to burn the data your DAO file contains to a CD-R or DVD-R.
