Users recommended method: using WINRAR compression package encryption method, practical and convenient, is more used by many people, can do without any encryption software !

I offer you the easiest way to use WINRAR. It is very convenient and easy to operate. I believe that your computer is already installed. Here's how to encrypt: 1 Right-click on the folder you want to encrypt and select Add to Archive. 2 Select the “Advanced” page and click “Set Password”. 3 Enter the password you want to set in the blank text box. Click "OK." 4 Click “OK” again, OK. 5 When you want to open it, double-click the file and a dialog box will pop up asking you to enter the password. After entering the password, click “OK”. 6 You can also add other files to it later. Simple, so encrypting others can't even see the title.

The official recommended encryption method:

First, encrypt the file or folder Step 1: Open the Windows Explorer. Step 2: Right-click the file or folder you want to encrypt and click Properties. Step 3: On the General tab, click Advanced. Select the "Encrypt content to protect data" checkbox

Also note the following five points during the encryption process: 1. To open Windows Explorer, click Start → Programs → Accessories. Then click Windows Explorer. 2. Only files and folders on the NTFS partition volume can be encrypted. The files and folders on the FAT partition volume are invalid. 3. The compressed file or folder can also be encrypted. If you want to encrypt a compressed file or folder, the file or folder will be uncompressed. 4. Files marked as "system" attributes cannot be encrypted, and files located in the systemroot directory structure cannot be encrypted. 5. When encrypting a folder, the system will ask if you want to encrypt its subfolders at the same time. If you select Yes, its subfolders will also be encrypted, and all subsequent files and subfolders added to the folder will be automatically encrypted when added.

Second, the decrypted file or folder Step one: Open Windows Explorer. Step 2: Right-click the encrypted file or folder and click Properties. Step 3: On the General tab, click Advanced. Step 4: Clear the "Encrypt content to protect data" checkbox. Similarly, we should pay attention to the following issues during the process of decryption: 1. To open "Windows Explorer", click "Start → Programs → Accessories", then click "Windows Explorer". 2. When decrypting a folder, the system will ask if you want to decrypt all files and subfolders in the folder at the same time. If you choose to decrypt only the folder, the encrypted files and subfolders in the folder you want to decrypt remain encrypted. However, new files and folders created within the decrypted folder will not be automatically encrypted.

The above is the method of using file encryption and decryption! In the process of using, we may encounter the following problems, here are the following instructions:

1. Advanced button can not be used Cause: Encrypted file system (EFS) can only process files on NTFS file system volume And folders. If the file or folder you are trying to encrypt is on a FAT or FAT32 volume, the advanced button does not appear in the properties of the file or folder. Solution: Convert the volume to an NTFS volume with a conversion utility. Open a command prompt. Type: Convert [drive]/fs:ntfs (drive is the drive letter of the target drive)

2. When the encrypted file is opened, the message "Access Denied" is displayed. Cause: The encrypted file system (EFS) uses the public key. The certificate encrypts the file and the private key associated with the certificate is not available on this computer. Solution: Find the private key of the appropriate certificate and use the Certificates snap-in to import the private key to your computer and use it locally.

3. The user solves the problem that the encrypted file cannot be accessed after reinstalling the system based on NTFS (Note: Be sure to back up the encrypted user's certificate before reinstalling Win2000/XP): Step 1: Log in to the computer as an encrypted user. Step 2: Click Start→Run, type mmc, and then click OK. Step three: On the Console menu, click Add/Remove Snap-in, and then click Add. Step 4: Under Separate Management Units, click Certificates, and then click Add. Step 5: Click “My User Account” and then click “Finish” (as shown in Figure 2, if you encrypt the user is not an administrator, this window will not appear, go directly to the next step). Step 6: Click Close, and then click OK. Step 7: Double-click "Certificate - Current User", double-click "Personal", and then double-click "Certificate". Step 8: Click the certificate that says “Encrypted File” in the “Expected Purpose” column. Step nine: Right-click the certificate, point to All Tasks, and then click Export. Step 10: Export the certificate and related private key in PFX file format according to the instructions of the Certificate Export Wizard (Note: It is recommended to use the “Export Private Key” method to export, so that the certificate can be protected by password to prevent others from stealing. Can only be saved to a directory where you have read and write permissions).

4. Save the certificate. Please save the PFX file. After reinstalling the system, just double-click the certificate file under which user, and import this private certificate to access the folder encrypted by the original user of the certificate under the NTFS system (Note: Encryption on the NTFS partition backed up using the backup recovery function) Folders cannot be restored to non-NTFS partitions). Finally, I would like to mention that this certificate can also be used for the following purposes: (1) Give different users access to the encrypted folder. Export my certificate as "export private key" and send the certificate to the folder that needs access to this folder. Other users of this machine. Then he logs in and imports the certificate to gain access to this folder. (2) On the WinXP machine, restore the encrypted folder to the previous encrypted folder backed up by the "Backup Recovery" program, back up the encrypted folder with the "Backup Recovery" program, and then copy the generated Backup.bkf together with this certificate. Go to another WinXP machine and restore it with the "Backup Recovery" program (note: only restore to NTFS partition). Then import the certificate to access the recovered files.
