Dopus Explorer replacement for applications

Will Dopus 10 replace Win7 64bit Explorer for opening and saving files within applications? ex: Thunderbird, Firefox, OpenOffice. It does replace it for desktop double clicks, Computer, and folders, but Win Explorer comes up within applications. Thanks.

Opus only replaces Windows Explorer the file manager, i.e.the default folder handler when folders are launched, and not other aspects of the Windows shell like File Open/Save dialogs used by apps to request a file/folder, or the taskbar, start menu, etc.
