A good question that deserves an upvote.

I don't have an answer but a possible explanation:

With drag & drop operations the drop target is responsible for performing the operation. This is the Windows Explorer for the trash bin. Moving a file to the trash bin is not a normal move (the original file information must be stored too). This process has been changed with Vista.

So all related operations are performed by the Windows Explorer and not by the system (ignoring the fact here that the Explorer is an essential part of the system). When the Explorer does not use the 'normal' system file operations but low level or system internal functions, you won't get them hooked.

Do you get a hook when deleting a file from within the Explorer?

I don't know what should I do when I drag and drop files to the recycle bin

The trash folder is a special folder where files are not handled like within other folders (except when deleting them finally). When deleting a file, it is moved to the trash folder (in fact the sub folder of the user performing the delete) using a new hidden name and the original file information (name and path, dates, attributes) is stored in the meta data. These meta data are read by the Explorer to show the folder content.

But I still can't answer why the behaviour differs between normal delete and drag & drop.

Can you observe the same while drag/drop in an other Folder than recycle bin?
