The solution is simple to wipe in Windows 10 / 8.1 without third-party tools to clearing free space and prevent recovery of files and folders!If you don't want use third-party tools, like the freeware ... BlankAndSecure to prevent recovery of files and folders in Windows 8.1 or 10. Use cipher via Command Prompt in Windows 8.1. For Example: cipher /W:C:\ to prevent recovery of files and folders on C:\ Drive. (... see Image-1) For a full access on drive: ... Windows 8 or 8.1 cmd.exe (command prompt) in administrator mode!
When you delete files or folders on Windows 8.1, the file and folder data is not initially removed from the hard disk. Instead, the space on the disk that was occupied by the deleted data is "deallocated." After it is deallocated, the space is available for use when new data is written to the disk. Until the space is overwritten, it is possible to recover the deleted data by using a low-level disk editor or data-recovery software.

By default, CIPHER continues executing even if errors are encountered. /C Displays information on the encrypted file. /D Decrypts the specified files or directories. /E Encrypts the specified files or directories. Directories will be marked so that files added afterward will be encrypted. The encrypted file could become decrypted when it is modified if the parent directory is not encrypted. It is recommended that you encrypt the file and the parent directory. /H Displays files with the hidden or system attributes. These files are omitted by default. /K Creates a new certificate and key for use with EFS. If this option is chosen, all the other options will be ignored. Note: By default, /K creates a certificate and key that conform to current group policy. If ECC is specified, a self-signed certificate will be created with the supplied key size. /N This option only works with /U. This will prevent keys being updated. This is used to find all the encrypted files on the local drives. /R Generates an EFS recovery key and certificate, then writes them to a .PFX file (containing certificate and private key) and a .CER file (containing only the certificate). An administrator may add the contents of the .CER to the EFS recovery policy to create the recovery key for users, and import the .PFX to recover individual files. If SMARTCARD is specified, then writes the recovery key and certificate to a smart card. A .CER file is generated (containing only the certificate). No .PFX file is generated. Note: By default, /R creates an 2048-bit RSA recovery key and certificate. If ECC is specified, it must be followed by a key size of 256, 384, or 521. /S Performs the specified operation on the given directory and all files and subdirectories within it. /U Tries to touch all the encrypted files on local drives. This will update user's file encryption key or recovery keys to the current ones if they are changed. This option does not work with other options except /N. /W Removes data from available unused disk space on the entire volume. If this option is chosen, all other options are ignored. The directory specified can be anywhere in a local volume. If it is a mount point or points to a directory in another volume, the data on that volume will be removed. /X Backup EFS certificate and keys into file filename. If efsfile is provided, the current user's certificate(s) used to encrypt the file will be backed up. Otherwise, the user's current EFS certificate and keys will be backed up. /Y Displays your current EFS certificate thumbprint on the local PC. /ADDUSER Adds a user to the specified encrypted file(s). If CERTHASH is provided, cipher will search for a certificate with this SHA1 hash. If CERTFILE is provided, cipher will extract the certificate from the file. If USER is provided, cipher will try to locate the user's certificate in Active Directory Domain Services. /FLUSHCACHE Clears the calling user's EFS key cache on the specified server. If servername is not provided, cipher clears the user's key cache on the local machine. /REKEY Updates the specified encrypted file(s) to use the configured EFS current key. /REMOVEUSER Removes a user from the specified file(s). CERTHASH must be the SHA1 hash of the certificate to remove. directory A directory path. filename A filename without extensions. pathname Specifies a pattern, file or directory. efsfile An encrypted file path. Used without parameters, CIPHER displays the encryption state of the current directory and any files it contains. You may use multiple directory names and wildcards. You must put spaces between multiple parameters. C:\Users\Hrg\Desktop> Prevent Recovery of deleted files under Windows 11, 10 Pro, Enterprise, Home, Windows 8.1, Windows 8, Windows-Server 2019, 2016, 2012, Windows 7 Basic, Professional, Starter, Ultimate In Windows 8.1 the Administrators can use Cipher.exe to encrypt and decrypt data on drives that use the NTFS file system and to view the encryption status of files and folders from a command prompt. An updated version of the Cipher tool has been released for Windows 2000, and is included with Windows XP. The updated version adds another security option. This new option is the ability to overwrite data that you have deleted so that it cannot be recovered and accessed. FAQ 173: Updated on: 21 July 2019 08:20 |
