CIPHER.exe – Windows CMD Command

Encrypt or Decrypt files and folders.
Without parameters, the cipher will display the encryption state of the current folder and files.
NTFS volumes only.

It is recommended that you always encrypt both the file and the folder in which it resides, this prevents an encrypted file from becoming decrypted when it is modified.

Cipher cannot encrypt files that are marked as read-only.
Cipher will accept multiple folder names and wildcard characters.
You must separate multiple parameters with at least one space.

The /W option will remove data on unused portions of a volume, effectively erasing data that still resides on a hard drive after deletion. See Q814599 for a description of this.
