Drag and drop treeview vb.net vs2010

I have a customer who requires that we can drag a file (pdf or word document) onto a windows form control ,which will then save the file to a directory and also populate the database with the relevant location.

I had though about using a treeview v control , but im not sure if that is the correct way of doing it .

Can give me any examples or help of what is the best way to do this ?

thanks in advance
Martin
