Win8 how to encrypt files Win8 disk encryption graphic tutorial

For many computer users, there may be some important files or privacy files. Many users often think of setting a computer power-on password in order to ensure data security. However, just setting the power-on password does not guarantee computer data security. Because setting the computer power-on password is only the simplest first threshold, once someone enters the computer security mode or takes a U system U disk into the PE mode, you can easily view and copy any files in the computer, and some users are accustomed to using mobile. Hard disk and USB flash drives store important private data, and once lost, they are exposed. Today, the editor of PepsiCo wants to introduce to you the BitLocker disk drive encryption tool that comes with Win7 or Win8 system, which can ensure the security of user data more effectively. Interested friends may wish to learn.

BitLocker encrypted disk or U disk or mobile hard disk, whether in PE mode or in safe mode require a password to open, greatly improved the data Security, and so far, using BitLocker encrypted files, no one can really crack, so it is quite safe at present, let's take the latest Win8 system as an example, teach you how Win8 encrypts files, Win7 system The same applies, XP system does not support.

Win8 enable BitLocker disk drive encryption method steps are as follows:

First, enter the Win8 control panel, and then click Start <; BitLocker drive encryption & rdquo; as shown below:
Enter Win8 After the control panel is enabled with BitLocker

, the BitLocker driver encryption setting window will pop up. We select the disk that needs to be encrypted and follow the prompts, as shown below:

In addition to encrypting our computer disk In addition, BitLocker also supports U disk encryption, we can directly enter the computer management, and then right click on the disk that needs to start BitLocker encryption, select to start BitLocker encryption, as shown below:
Encrypt U disk or removable hard disk Method

Whether it is for disk encryption or U disk encryption, the following device steps are the same. Here we take the U disk encryption as an example, let's take a look at the BitLocker encryption setup wizard.

Second, after selecting the disk or USB flash drive to be encrypted, the following BitLocker encryption setup wizard will pop up. There are two encryption methods, one is &ldquo "Use a password to unlock the drive"; another is "Use a smart card to unlock the drive", here we usually use a password to unlock the drive, and for "Use smart card to unlock the drive", you need a special encryption card to insert into the computer motherboard In the middle, it is a common security encryption method used by some companies. Individual users do not need to be so troublesome. Below we introduce the choice of the first password encryption method, as shown below:
Select encryption method

Third, when we choose "Use password to unlock the drive", then you need to enter the encryption password, in order to ensure The security of the account password, it is recommended that you set the password as complex as possible, of course, you must remember it yourself, as shown below:
Enter the encrypted password

Fourth, click the password after entering the password. In one step, enter the “Backup Recovery Key” window, where we need to back up our own key to facilitate recovery. After all, you have set up a very complicated password, in case you forget what to do, don’t Thinking about cracking, so far, there is no good way to crack BitLocker encryption, so don't be sloppy here, as shown below:
Backup recovery key settings

5. In order to ensure that the user account password is not forgotten and cannot be retrieved, Win8's BitLocker also has a similar password recovery function. We can save the password as an account or a certificate. Wait, it is convenient to forget, you can import and retrieve, this function is similar to the password recovery function, as shown below:
Save password backup file

We can save the set encryption password as a file or Microsoft account, etc. As shown above, generally recommend that you choose to “save the recovery key to the file”, so you can save the key to the local hard disk in the TXT file format. It is easy to forget, you can check it, but it is best to place it with the computer. Concealed in the file.

Ps: Here we must not save the files saved in the password on the encrypted disk, otherwise you can see the password yourself. This is something you need to remember.

Six, in the next operation, we will prompt us to encrypt the disk space size, if you want to save disk space, you can choose to "encrypt only used disk space", and if you have important inside the disk There are a lot of files, you can directly choose to encrypt the entire disk, as shown below:
Select Win8 disk encryption space size

Seven, click "Next" & rdquo; continue to complete the BitLocker Disk Encryption Wizard settings, and then in the next interface Click “Start Encryption" as shown below:
Select “Start Encryption&#&#> Encrypting Disk

The BitLocker encryption process that comes with Win8 system takes a while, you need to wait patiently for a while. During this period, try not to interrupt or manipulate the files on the encrypted disk to avoid errors, as shown below:
Successfully complete the encryption of the specified disk

After the encryption is completed, we can see it in the computer disk management, we just saw There is already a lock graphic mark on the set removable disk. After entering the U disk, you need to enter the password we set to enter.
The disk after successful encryption will have a lock flag

The above is finished. If Win8 disk or U disk is encrypted, sometimes we don't have any important data. We don't want to encrypt it. How to solve it? ? The method is also very simple, as briefly introduced below.

Remove the BitLocker disk encryption method:

1, enter the computer management, and then have the encrypted disk or U disk drive letter Click the right mouse button, and then select “Manage BitLocker” as shown below:
Right click on the disk and select Manage BitLocker

2. After entering the management BitLocker interface, we can find the disk or U disk drive letter that needs to be closed, then Click “ Close & rdquo; as shown below:
Select the corresponding disk to close BitLocker

3, after which you will be asked to enter the encrypted password, after the completion will begin to reveal the secret, if the previously encrypted files are more, then Decryption can take a long time, but you can also do some other computer operations during the decryption process.
Be sure to close BitLocker

4, follow the prompt of the decryption wizard, step by step, the next step can successfully complete the disk decryption. After the decryption is completed, you will not need a password to enter the disk.
Decrypting the specified disk decryption completed

Editor: BitLocker file encryption is a function to protect user data security in Win8 system. The default is not enabled, and we have already known BitLocker encryption under Win7. Differently, it mainly adds support for cloud account protection in password backup, ensuring that passwords are not easy to forget. If you have important data in your computer that needs to be encrypted, then the BitLocker encryption tool that comes with the Win8 system is a good choice. Introduced here I believe that everyone will have to encrypt the file for Win8.
