.dna File Extension

Developer: Computer Associates
File type: CA Backup and Migration Backup File
You're here because you have a file that has a file extension ending in .dna. Files with the file extension .dna can only be launched by certain applications. It's possible that .dna files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .dna file?

CA backup and migration backup files can be created using the CA Backup and Migration software from Computer Associates. These files are saved using this application in the DNA format and are appended with the .dna extension. Classified as backup files, the content of a file in the DNA format includes the settings of hardware and software components of a computer. The CA Backup and Migration program can also be used by Microsoft Windows users to open these DNA files. When opened, this software automatically migrates the settings and configurations stored in the DNA file to the system of the computer. Users of computers running on Microsoft Windows-based systems can also install and use the CA Desktop DNA Migrator, also developed by Computer Associates, to create, open and edit the content of a DNA file. The data in these DNA files may also include network configurations like administrator usernames and passwords and user or guest account credentials, and authors of DNA files can enter folders containing files like images and audio content as well as address and phone book data in a DNA file using these applications in Microsoft Windows systems. A DNA file is also integrated with automatic self-extracting functionalities.

CA Backup and Migration

CA Backup and Migration

CA Backup and Migration is software that was developed by Computer Associates which aims to provide its users with a tool that will give them the capability of sharing data with up to a maximum three different computers which at the same time is capable of backing up the files. This tool supports 5 different languages which include English, Spanish, Italian, German and French. The software needs a 32-bit Windows Operating System to work. It has a practical assistant which is responsible for the sharing of the data with the other computers and the same time in backing up the copies of the files in the main computer together with the different options for the configuration and this process can be done even if the other computers where those data will be transferred to have a different Operating System than the main one.

a word of warning

Be careful not to rename the extension on .dna files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .dna. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
