The Extensions Settings allow you to enter what video, audio, image, and other file extensions you want CaseGuard Studio to recognize when you’re working in the program. You’ll notice that all major open-source formats are already entered by default. You can add as many file extensions as you’d like. To learn how to do this, read Supported Media Formats.
