Open (Sub) Folders During Drag'n'Drop Hover?

[thinkstorm]

I am constantly annoyed that when I drag'n'drop files around - for example from the desktop to my documents - I have to first make sure I have the right subfolder open in the target windows explorer window.

When the target explorer has the "folder tree" window on the left, folders that have a "+" sign are automatically tried to expand after I hover with my dragging files/links over the folder for 500ms. Unfortunately, this only works in the folder tree view. When I hover with my dragged files over a folder symbol in the actual windows explorer window, the folder stays closed.

Isn't there a shell extension out there that automatically opens the subfolder after xxx miliseconds while I hover with the drag files over a folder symbol???

Cheers,

Thorsten
