This is how Armory's DB has always worked. It copies all block data over to its own DB. If you want to light version, build 0.94 from source and try it out, it's in the ffreeze branch.
Just to be clear, Armory developers see the issue with how big and how much GB the chain takes up locally right? Hence a "light" version is around? If in fact this is how Armory is why can't there be a setting to point that folder to another location? Why does it have to be on the local drive? Even if Armory is installed on another drive, it still makes these files on the primary drive. I run many portable programs. Can't Armory do something like that? And the chain is only getting larger and larger.
I did see your other comment in the other thread. Looking for the different switches I can use.
