Solution to the problem that encrypted files cannot be accessed after the system is reinstalled. Users can encrypt files based on NTFS. After the system is reinstalled, encrypted files cannot be accessed, you can use the following methods to back up the encrypted file key certificate and import the key certificate to restore the access permission to the encrypted file. However, if you do not have a backup, the encrypted file cannot be accessed after the system is reinstalled, only the restoration software can be used for scanning and recovery, such as ERecovery and FinalData.
Step 1: log on to the computer as an encrypted user. Step 2: Click Start> Run, type mmc, and click OK ". Step 3: on the "console" menu, click "Add/delete Management Unit", and then click "add ". Step 4: Under Unit management, click certificate, and then click Add ". Step 5: Click my user account, and then click Finish. 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 with the words "encrypted file" displayed in the "expected purpose" column. Step 9: Right-click the certificate, point to "all tasks", and click "Export ". Step 10: follow the instructions in the certificate export Wizard to export the certificate and related private keys in the PFX file format. Note: We recommend that you use the export private key method, this ensures that the certificate is password-protected to prevent theft by others. In addition, the certificate can only be saved to a directory with read/write permissions ). Save the PFX file. After the system is reinstalled in the future, you only need to double-click the Certificate file under any user, and import the private certificate to access the folder encrypted by the original user under the NTFS system, this certificate can also be used for the following purposes: (1) grant different users the permission to access the encrypted folder and export my certificate in the "export private key" mode, send this certificate to other users on the local machine who need to access this folder. Then, log on to and import the certificate to access the folder. (2) restore access to the previously encrypted folder backed up by the "Backup Recovery" program on its WinXP host by using the "Backup Recovery" program to back up the encrypted folder with the "Backup Recovery" program, then, the generated Backup. bkf copies the certificate together with the certificate to another WinXP machine and uses the "Backup Recovery" program to restore it (Note: Only the NTFS partition can be recovered ). Then import the certificate to access the recovered file. Author shanblue
