I can't dump keys. I installed pywallet but when I click on "Dump Keys" i get "File not written" error.
Maybe it happens because .bitcoin directory is a symlink. So i tried to enter the right path, but the same error occurs.
Any other way to do the same?
Change Addresses are a pain. One of the things that I like about Electrum, is that you don't have to use them. Most wallets, however, create NEW addresses EVERY TIME you make a spend, and some of your bitcoins go into hidden 'change' addresses.
The best way to move money into a new wallet is to send the funds. Don't try to import the keys unless you know what you're doing.
If you want to check the actual balances on your individual addresses to determine the actual balance of the imported keys, then go to this webpage and enter your public keys of the addresses that you want to check.
