1. what should i do for move my pc-wallet to another PC (i have phoenixcoin-qt.exe for windows). Just copy full directory? (including all data files? wallet.dat blk0001.dat etc...)
2. on my PC (win7-64bit) installed "phoenixcoin-win-0.6.6.1.zip", wallet not for 64bit, but it works. is it necessary to use "phoenixcoin-win64-0.6.6.1.zip" for 64bit systems?
1. Exactly. Just copy the entire directory.
2. Not necessary, but a native 64-bit executable shouldn't be any worse than a legacy 32-bit executable running on a 64-bit OS.
