Double-click Files

The options on this page let you control what Opus does when you double-click on certain types of files in a file display. The File Types system gives you far more control over double-click actions than this page.

• Open unregistered file types in text viewer if they appear to be plain text: If you double-click on a file of an unregistered type (or one without a file extension), Opus will examine its contents, and if it looks like a plain text file it will treat it as one, and open it in the default text viewer (usually Notepad). This is particularly handy for files from other file systems that don't necessarily have a .txt extension. If you want to use a text viewer other than the default you can select one to use.
• Use internal sound player for WAV files: If this option is on and you double-click on a .wav file, Opus will play the file in its own simple sound player rather than opening the normal media player application.
• Use internal picture viewer: Similarly, you can choose to have Opus use its own picture viewer when you double-click on image files rather than launching whatever the default application is. You can choose to have this happen for all recognized image files, or only unregistered file types.
