I totally agree with oded_904 and the original question from Carolyn! There should be a "PROMPT" when dragging and dropping entire network folders because users don't even realize they are doing it.
Just incredible that Microsoft don't pick this up and give the option to ask for confirmation!
It does beg the question does anyone 'that matters' actually read these comments?
I am retired IT Pro, but right up to the day I retired I would spent pointless time trying to solve a customer's problems caused because they have accidentally moved a folder. In XP you had a little warning in Windows 7 you don't even have that.
I cannot blame my customers because I have done it myself and of course if you don't spot it and use undo, you are in for problems.
A Very Bad omission from an otherwise largely user friendly package.
