Bitcoin QT backup problems.

[chessnut]

Hi folks,

I have an old bitcoin wallet software by the name 'Bitcoin QT', and I would like to move the address and private key in that wallet to my new wallet software 'Multibit' However, the backup file that Bitcoin QT produces will not open - "file type unknown". I cant find any way of using that backup folder, or even viewing the contents. If I try moving it to my Multibit wallet software, it simply does nothing.

Can somebody please give me a tip?

Thanks!

just copy and move your wallet.dat to other drive.

Bitcoin-Qt and MultiBit do not use the same wallet files.  You cannot import the wallet.dat file from Bitcoin-Qt into wallet.dat.

If you still have the Bitcoin-Qt program running, you can export the private keys from the wallet.  Then once you have the private keys, you can import their values into MultiBit.

Exporting private keys from Bitcoin-Qt is not part of the user functionality.  You will need to either use server mode or the Console in the Debug Window to issue API calls.  Here is information about the available API calls that you can make:

Busy looking for an easy way?  Cannot find one? Where exactly are you looking?
