Though I have not seen any hook implementation for this global file operations and also ICopyHook which available is only works for Folder and Printer objects....
But You may check out API SHChangeNotifyRegister() which sends notifications from the file system or shell about particular operation..this will help you to implement hook..

Hi, but seems SHChangeNotifyRegister() can't detect "copy file", "cut file" "open file" event, Could you give me example code? Thanks~

I found someone want hook double click's solution
--------------------------------------------------------------------------------------------------------------------------
You have to implement IContextMenu (return the interface in GetUIObjectOf) and put a default item in it. Normally the flag CMF_DEFAULTONLY will be set, and then you add only your default command. Then in InvokeCommand you display your dialog.
Of course, nowadays it is advised to use CDefFolderMenu_Create2 for your context menu.

But I'm beginner to shell extension/COM, so can anyone give me sample code explain above solution?
Thanks~
