What is DNA file?
The DNA file has been categorized as Backup Files. It was designed by Computer Associates. In addition to this file, the Backup Files category includes 243 related files. CA Backup And Migration Backup Format is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others. The main program that supports this format is CA Backup and Migration. This was created by CA Technologies. There are also 1 alternative programs to handle the DNA file. CA Desktop DNA Migrator will apply when it is not possible to use CA Backup and Migration.
How to open DNA file?
The most common problem when using CA Backup And Migration Backup Format is that a specific DNA is not associated with the program. This causes the file DNA to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the DNA file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install CA Backup and Migration
An often overlooked issue is to make sure that CA Backup and Migration is installed on the computer. To do this, enter the name CA Backup and Migration into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DNA with CA Backup and Migration. Below you will find a list of applications that support DNA files.
Programs to open DNA file
Remember to download programs supporting DNA files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of CA Backup and Migration with DNA files
If the application is or has been freshly installed, but the DNA file still does not use the CA Backup and Migration program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the DNA file with the CA Backup and Migration program.
Step 3. Update CA Backup and Migration to the latest version
If, however, after binding CA Backup and Migration with CA Backup And Migration Backup Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the CA Technologies page and install.
Step 4. Check for the following problems with the DNA file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the DNA file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file DNA or the program directory. As a result of the scan, sometimes it is not possible to recover DNA files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of DNA file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged DNA files. The easiest way to restore the file is from a backup or by contacting Computer Associates, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file DNA except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the DNA file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the DNA file while scanning. If the problem persists, restart the machine.
