.DNA File Extension

File created by CA Backup and Migration, a program used to backup a computer's "DNA"; contains network, printer, system, and application settings as well as files, folders, address books, and photos; used for backing up computer settings and transferring settings from one computer to another.

DNA files are self-extractable. When opened, they automatically migrate the backed up settings and files to the new computer.

Data file used by GenePool, an artificial life simulation game; contains the DNA for a creature that can be simulated with other creatures in a virtual experiment; sometimes used for competitions to see which player's custom creatures survive better than others when simulated together.

NOTE: DNA files are also used by Darwin Pond, the predecessor to GenePool. However, Darwin Pond DNA files use a plain text format while GenePool DNA files use binary formatting. The Darwin Pond DNA files contain a fixed list of parameters separated by line breaks, and each file has the same file size.
