In my Armory installation, it is maintaining what appears to be a copy of the blockchain at %UserProfile%\AppData\Roaming\Armory\databases\leveldb_blkdata as well as  %UserProfile%\AppData\Roaming\Bitcoin\blocks.

Option-wise, I have "Let Armory run Bitcoin-Qt/bitcoind in the background" and I have left both the install dir and home dir blank. The region beneath the directories defined as "Leave blank to use default datadir (...)" does have the correct \Roaming\Bitcoin directory present.

When I start Armory, files are updated in both directories, I only want to keep one. This is not a complaint about speed or load time, I'm just trying to recover bytes by correcting whatever is wrong with my setup. Any suggestions?
