That's great and thanks for your help, the information is in https://bitcoinarmory.com/tutorials/armory-basics/move-files/

tl;dr How do you tell Armory to use a blockchain on a specific drive?

First let me say I have got Armory working with no problems at all. My problem is that I have an SSD in C: so I want to run Armory, bitcoin and store one copy of the blockchain on E: to save space on C:

bitcoind
---------
Bitcoin-qt is in E:\Program Files\Bitcoin with bitcoind.exe in E:\Program Files\Bitcoin\daemon
bitcoin has a copy of the blockchain in E:\Users\Me\AppData\Roaming\Bitcoin

Armory
--------
Armory is installed in E:\Program Files (x86)\Armory\ArmoryQt.exe
I have got my wallets and another copy of the blockchain in C:\Users\Me\AppData\Roaming\Armory (which seems to be the most up-to-date)
I have got my wallets and a third copy of the blockchain in E:\Users\Me\AppData\Roaming\Armory

Armory is running bitcoind in the background.
I have entered the Bitcoin Install Dir as E:\Program Files\Bitcoin and the Bitcoin Home Dir as E:\Users\Me\AppData\Roaming\Bitcoin

Problem: Although Armory is running from E: and so is bitcoind, I can't figure out how to make Armory use a copy (share a single copy ideally) of the blockchain on E: Armory seems to be using the orginal copy on C: which I want to delete and the bitcoin-qt/core client has created its own copy.

Anybody any ideas? I don't use bitcoin-qt/core, it just starts downloading the blockchain when you upgrade it. I am on Windows 7 64-bit. Thanks.

Thanks for your prompt reply. I have also discovered in 0.91.1 that

—performing a Wallet Recovery > Select Loaded Wallet brings up no data fields and no Spendable BTC.
—a Full Recovery then results in "Wallet is consistent, nothing to fix" but all transaction balances are set to 0 (zero) with a 0.00 wallet balance.

Quitting and restarting Armory will correct this and cause the previous balance to be displayed in that wallet again. This leads me to conclude there are other potential problems with 0.91.1 which are that

• when selecting a Loaded Wallet for recovery its Wallet ID, Name, Description and Spendable BTC balance are not displayed
• carrying out a Full Recovery on a wallet that has passed the initial Wallet Consistency Check causes all transaction balances to be displayed as 0 (zero) with a 0.00 wallet balance until Armory is restarted

This is in addition to the problem above. Thanks.

I have just upgraded to 0.91.1 and one of my wallets was corrupt. I tried to repair it and eventually restored it from a paper backup. I think about 90 per cent of my bitcoins are missing from the wallet. I think this is because no change has been restored to the wallet.

For example https://blockchain.info/tx/ca1c362e6c9130d1bee164613e1143ed60f6838bf129aba28791a8e0542174fb I sent 0.007727 BTC from 16Rj.. to 15jd.. and received 0.076973 in change to 14B1.. but 14B1.. is no longer associated with the spending wallet.

I don't know the cause of this yet and I have opened a support ticket but I just want to send a word of caution - if Armory is working fine and you haven't upgraded yet, then think twice—unless you know what caused my problem and if you do, can you please let me know

On the Imported Address Warning, it would help if

'If you do not plan to use the address again, it is recommended that you "Sweep" the private key instead of importing it'

was changed to

'If someone else might know this address, it is recommended that you sweep the private key instead of importing it'
