Is there anyway to use the same blocks or block files for other every coin that has a QT wallet?
There is a way using symbolic links, but I wouldn't recommend it as it will likely just corrupt your block files. So in practice, there isn't. All you an do is copy and paste the data directory. When you do that, you have to make sure that the data directory you copy does not have blocks that would be invalid to the forked coin, i.e. there are no blocks after the forking point.
