Drag-Move Long File becomes Copy

[meteorquake]

If I drag-move a bunch of files where one of them has a long total path (just over normal), to a folder (that may have a short path), the move for all of them becomes copy. I can shift-drag and it changes to the normal move. If I shorten the offending file to a normal length it all works as normal.
This doesn't sound expected to me, and caught me by surprise.
It's possibly what is happening in the unresolved bug report at viewtopic.php?t=12789

The drag-drop operation is completed by the system with GetUIObjectOf/IID_IDropTarget.

I will consider handling the drag-drop operation with Everything.
(at least for files with really long names)

Thank you for the suggestion.
