I want to move Ether between different wallets. I have a private key and want to move it to the Mist wallet. Any way I can do that?
Copy your private key into a file, eg privatekey.txt
In Linux or Mac, from your Ethereum Wallet (Mist) subdirectory, type
./resources/node/geth/geth account import privatekey.txt
In Windows, from your Ethereum Wallet subdirectory, type
resources\node\geth\geth.exe account import privatekey.txt
In both the above options, you will have to enter a password twice to encrypt your new account information.
You can now start Ethereum Wallet and the new account will be loaded into the wallet.
Remember to delete privatekey.txt after you have successfully imported your private key
