The AD file extension stands for After Dark Screensaver. It contains encoded data in the AppleDouble format with the data fork that makes it possible to open in non-macOS UNIX environments. AD files are also used by Visual Studio for application diagrams and Unity game engines for assets.
To open an AD file, associate it with the correct application. On Windows, right-click the AD file then “Open with” and “Choose another app.” On Mac, right-click the file, click “Open with” then “Other.” On Linux, right-click the file and select “Open with.” On iPhone, tap the file. You can also check “Always open with” to set the default program.
If the system has heavy load, it may not handle the program for AD files. In that case, close other applications first. Check for the latest updates to the operating system and drivers which may help as well. Opening unknown file types can be difficult. Many files contain only simple text.
