Ok ...
Just to confirm - you received access denied when trying to drag to say your
desktop (where you can easily confirm that you can create a new file on that
desktop and have permission, but it still returns access denied).
Just out of curiosity, try dragging one of those restricted files to the
following folder:
%userprofile%\AppData\LocalLow\
And see if that works.
