After installing the bitcoin client (Qt) a friend got interested as well. He doesn't have as fast an internet connection, though, so I thought of burning some DVDs with the blockchains for him to have.
I saw this question on how to transfer blockchain from PC to Mac and the solution was to copy the whole "Bitcoin" folder. However, that folder also contains MY wallet as well (which I definitely do not want my friend to have, even if encrypted).
So I'd like to know, which folder(s) and/or files do I need to copy, minimally, so he needs to get as few blocks over the network as possible? If it's too much of a hassle, most probably I'll suggest him to use multibit or electrum instead :-)
10To be more specific, you need to transfer the
blocksand thechainstatedirectory. Don't transfer thedatabasedirectory as it may contain remains from wallet.dat such as private keys. – wumpus – 2013-05-11T06:45:29.327The first comment is technically a "clearer" answer because it provides instructions in the affirmative (i.e. "copy only X and Y") instead of via negation (i.e. "copy everything except "L" and "M") - since the second set of instructions the user only knows what to copy by inference. However both are technically correct! Just a note for future answers and interested readers. – GrayedFox – 2018-03-15T01:55:52.220
1What about tx index on running wallet ? I suppose it will result in corrupted index, since the copying will run for hours anyway – Pavel Niedoba – 2019-03-11T13:52:04.203
