Displays or alters the encryption of directories [files] on NTFS partitions.      CIPHER [/E | /D] [/S:directory] [/A] [/I] [/F] [/Q] [/H] [pathname [...]]        CIPHER /K        CIPHER /R:filename        CIPHER /U [/N]        CIPHER /W:directory        CIPHER /X[:efsfile] [filename]            /A        Operates on files as well as directories. 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.      /D        Decrypts the specified directories. Directories will be marked                so that files added afterward will not be encrypted.      /E        Encrypts the specified directories. Directories will be marked                so that files added afterward will be encrypted.      /F        Forces the encryption operation on all specified objects, even                those which are already encrypted.  Already-encrypted objects                are skipped by default.      /H        Displays files with the hidden or system attributes.  These                files are omitted by default.      /I        Continues performing the specified operation even after errors                have occurred.  By default, CIPHER stops when an error is                encountered.      /K        Creates new file encryption key for the user running CIPHER. If                this option is chosen, all the other options will be ignored.      /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.      /Q        Reports only the most essential information.      /R        Generates an EFS recovery agent 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 agent for users, and import the .PFX to                 recover individual files.      /S        Performs the specified operation on directories in the given                directory and all subdirectories.      /U        Tries to touch all the encrypted files on local drives. This will                update user's file encryption key or recovery agent's key 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.                  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.
