I haven't played with Win 7 a lot but finally upgraded the desktop to win 7 last weekend and it killed itself trying to install updates so back at it again this weekend.
From my limited knowledge of win 7 check the permissions for each folder you are trying to move between. Creating a new folder is a good suggestion because you can set the permissions the same.
Also if you are using wireless to be your home network then you could be have connection problems stopping the transfer or it is just taking too long.
I am by no means an expert but I am sure someone around here has a fix for you. I btw still don't like to network my home computers (windows still doesn't have that figured out imo) so I personally use a 1TB portable harddrive. Maybe that will change with everything being on win7 for me now?
