I downloaded the entire Bitcore block data - 124 Gb.  I am now able to see my transactions in Armory (which I couldn't before the download).  I moved my Data to a USB drive because of its size.  I used (G:\Bitcoin\bitcoin-qt.exe -datadir=g:\BitcoinData) in the Bitcoin target command to recognize the data area, which worked and kept the data off my small operating drive.  When I start Armory, however, I get an error message that it has lost connection with Bitcoin Core client.  When I start Bitcoin Core up it acts as though there is no data and starts re-loading the data (3+ days).  I am unable to send coins from my Armory wallet because the Armory software shuts down.

Thanks for any help.

I don't know if this will apply to you, but I've noticed that after having moved the blockchain data to another drive that my system can't seem to find the folder on the drive. But if I manually search for the blockchain location (using file explorer in your case) and then drill down from the drive level to the folder containing the blockchain, my system seems to "catch up" and recognise that the folder does actually exist. Hope this helps.

You will need to always start Bitcoin Core with the -datadir option in order for it to know where the datadir is. It will not remember the datadir location from a previous run.

You will need to always start Armory with the --satoshi-datadir=<path> option (where <path> is the path to the Bitcoin Core datadir) in order for it to know where the block data is stored so that it can read the blocks and get other information to connect to the Bitcoin Core node.
