What is an ADR file?

The .adr file extension is used for a digital video file format. These ADR files are also called After Dark random screen saver module files. The .adr file format was created by Berkeley Systems in 1989 for their suite of After Dark screen saver software programs, which were designed for Apple Macintosh computers. Berkeley Systems also developed in 1991 versions of their After Dark screen saver programs for Windows PCs. They also created a version of the ADR file format that can run on Microsoft Windows environments. These .adr files contain digital videos and code that can allow the digital video content to be automatically played when a computer is idle for a specified time. Some versions of these After Dark screen saver tools are also equipped with password-locking functions. The suite of After Dark screen saver programs from Berkeley Systems can be used to open and view the content of these ADR files. There are no known applications that are able to export these ADR files to other more standard digital video file formats.
