I know that by default the wallet.dat is stored in C:\Users\YourUserName\Appdata\Roaming\BitCoin

To secure this wallet, do I remove the wallet.dat (eg. ctrl + x the file) away from C:\Users\YourUserName\Appdata\Roaming\BitCoin and then put it in an encrypted folder on multiple HDs to prevent theft?
If I do this then do I copy the wallet.dat back into the default folder to add BTC to the wallet, then remove the wallet again and encrypt the updated version?

So basically if I open the Bitcoin app, since there is no wallet.dat will it just show up as having 0 BTC unless I manually copy the wallet.dat back over to the default directory?
