Directory Opus File Types

As well as the registered file type extensions and groups, there are a number of psuedo-file types that Opus defines. These are listed at the top of the File Types dialog.

Changes that you make to these file types will affect general classes of file rather than specific types. They are:

• All files: All files belong to this class. Changes that you make to this will affect all types of file (but not folders).
• All files and folders: All files and folders belong to this class - changes you make to this will affect all files and folders throughout the system. The "standard" context menu commands like Cut/Copy/Paste are implemented through this class, as those are context menu commands that are relevant for any file or folder.
• All folders: All folders belong to this class. Changes that you make to this will affect all folders but have no effect on files.
• Collection item: This class affects items that are stored in Opus File Collections. The normal use of this class is to add context menu items like Remove from Collection.
• Recognized images: This class contains all image types that Opus recognizes. It's similar but not identical to the Images group. Although the Images group defaults to containing most image formats Opus understands, you can add any file extensions you like to it - whereas the Recognized images class automatically contains all recognized image formats and no others.
• Unknown file types: Any unregistered file types belong to this class. For example, if you have a file called myfile.bumblebee and .bumblebee isn't a registered file extension, files with that extension would automatically belong to this class.
