What is a DA0 file?
DA0 is an extension characteristic of files used in older Windows operating systems (95/98 / ME). DA0 are files where the system registry was backed up. Windows created these files automatically each time it was properly started. Files of this type can be the basis for repairing a damaged system registry. The registry is one of the most important elements of the system responsible for its correct operation.
A DA0 file is a backup of the original registry file with the DAT extension.

How to open DA0 files
If you cannot open the DA0 file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports DA0 among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the DA0 file can be found in the table. Now just download and install the appropriate application.
Possible problems with the DA0 format files
The inability to open and operate the DA0 file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft Windows 9x Registry Backup Format file. Below is a list of possible problems.
- Corruption of a DA0 file which is being opened
- Incorrect links to the DA0 file in registry entries.
- Accidental deletion of the description of the DA0 from the Windows registry
- Incomplete installation of an application that supports the DA0 format
- The DA0 file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the DA0 file.
- Drivers of equipment used by the computer to open a DA0 file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the DA0 file should operate with your programs without any problem. If the problem with the DA0 file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DA0 file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.DA0) you have two ways to do it. The first and the easiest one is to right-click on the selected DA0 file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the DA0 file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. DA0) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
