ReadOnlyChecked: Boolean;

The property is relevant if the ShowReadOnly property is set to True. The ReadOnlyChecked property is set to False by default, and the checkbox is deselected. If the property is set to True, the checkbox is selected. This property can be used to check the mode of opening the files selected in the dialog box.
The example of use is given in description of the IFileOpenDialog.MultiSelect property.
