Did you find a DAA file on your computer and wonder what program should open it? Maybe someone emailed you a DAA file but you're not sure how to use it. Perhaps you tried to open the DAA file but Windows told you that it could not open it.
Before you can open a DAA file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .DAA file extension refers to.
Direct Access Archive files are much like ISO files in that they are images of discs, but have some advantages over ISO like compression and file splitting abilities.
Other types of files may also use the DAA file extension. If you know of any additional file formats that use the .DAA extension, please let me know so I can update this information.
How To Open a DAA File:
The easiest way to open a DAA file is to double-click on it and let your PC decide which default application should open the file. If no program opens the DAA file then you probably don't have an application installed that can view and/or edit DAA files.
Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.
Direct Access Archive DAA files can be opened, created, managed, and burned to disc by the Power ISO program. The Direct Access Archive format is a proprietary one developed by the same people that created Power ISO.
Even though DAA files are designed strictly for Power ISO, there are a few methods for converting DAA files to ISO format, which you can then burn to disc with any number of free programs. The methods are outlined here and here.
Once you've converted the DAA file to ISO format, see How To Burn an ISO Image File to a CD, DVD, or BD for help.
If you know of anything else useful about DAA files, please let me know so I can update this page.
Tip: Use Notepad or another text editor to open the DAA file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This won't be the case if your DAA file is a Direct Access Archive disc image, but if it's not, give this idea a shot.
If you find that an application on your PC does try to open the DAA file but it's the wrong application or if you would rather have another installed program open DAA files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.
How To Convert a DAA File:
There are two main ways to attempt to convert a DAA file to another file type:
- Open the DAA file in its default program and choose to save the open file as another file format.
- Use a File Conversion Online Service or Software Program to convert the DAA file to another file format.
The first option involving opening the DAA file in its native program (PowerISO) is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens DAA files, a third-party file conversion tool (the second option) could be very useful. Be sure to see the discussion above about converting DAA files to ISO.
Important: You cannot usually change a file extension (like the DAA file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
