Windows can't open your APMASTER file?

When you try to open a file by double-clicking it, Windows looks at the file's name to figure out what to do. If Windows doesn't know the file type, it'll ask you to choose an app to open this APMASTER file.

To set the APMASTER file association in Windows 11, you can follow these steps

  1. Open the Settings app by clicking on the Start menu and selecting the gear icon.
  2. In the Settings app, click on System and then select Apps from the left-hand side menu.
