4. At present, the data capacity of bitcoin blockchain continues to grow. Now it's about 10g. When many friends install the system, Disk C is not set very large. Are you worried that disk C will explode one day. Now learn how to do data migration with me First, close bitcoin client)

1. Find bitcoin's data folder< br />
XP---C:\ Documents and Settings\ username\ Application Data\ Bitcoin

vista,win7---C:\ Users\ username\ AppData\ Roaming\ Bitcoin
(Note: appdata is hidden, set to show hidden files.)

2. Cut this bitcoin folder to other drives with large space, such as disk E

3. Edit the bitcoin shortcut on the desktop, the following line to the "target" column, and then save it:

& quot; C:\ Program Files\ Bitcoin\ bitcoin-qt.exe" - datadir=e:\ Bitcoin

now, double-click the bitcoin shortcut on the desktop, the client will start, and your C disk will be saved, releasing space successfully.

5. First of all, you should imagine a concept of "wallet" in your brain. Your bitcoin is in your wallet. A wallet can contain many... Many addresses. As long as the address is generated by your client and other people pay to the address, they will remit money to the wallet. Where is your wallet? If you are using the Windows client, please click the start menu, find "run", and then enter% appdata% &; Bitcoin click "OK" and you will find a file called wallet.dat, which is your "wallet". The wallet stores all the keys used to prove that you have the money contained in the wallet. You need to do two aspects of work at the same time: 1. Ensure that the wallet will not be lost; 2. Ensure that the wallet will not be obtained by others. The method is: encrypt the backup. Relatively simple and effective one is: 0, install anti-virus software, thoroughly kill a virus, keep anti-virus software running 1, close bitcoin client 2, use winrar encryption compression. Please remember to use the password with enough security, and the password should not be retarded. Then back up the encrypted file to a secure U disk. 3. Delete the wallet.dat in disk C. when you need to pay bitcoin, 4. Is it troublesome to decompress the backup wallet.dat into the folder mentioned above? Yes, it's so troublesome, because bitcoin currency system is still at an extremely early stage. It's invented and accepted by some technology enthusiasts, and they haven't had time to take care of the feelings of ordinary users. All of this will become easier to use in the future. However, the next version of bitcoin client is ready to build in the integrated wallet encryption function, which will be much easier for ordinary users to back up. As long as you make sure that your computer has no Trojan horse and set a strong enough password, it is largely safe. Gavin also plans to introce a two device authentication mechanism, that is, to divide your wallet into two parts that are encrypted and protected, one part in your computer, and the other part in other devices, such as mobile phones. Just like the SMS verification launched by some online banks, to complete the payment, two devices need to confirm at the same time. This is not troublesome for the actual owner of bitcoin, but for the thieves, they need to steal the files of two devices at the same time to steal the key. In addition to the acquaintances around you (you must also know your password), that is basically an impossible task. It is expected that there will be reliable bitcoin online storage in the future, and even traditional banks may launch bitcoin escrow service, which will be much more convenient at that time
