What does the Windows command 'Cipher' do?

• A. Encrypts files for security
• B. Overwrites hard drive data for permanent deletion
• C. Compresses files to save space
• D. Restores deleted files

Answer: (B)

The Windows command 'Cipher' is primarily known for its ability to encrypt files within NTFS file systems, providing an additional layer of security. By using this command, users can ensure that sensitive data is protected and unauthorized access is prevented. The encryption is handled through the Encrypting File System (EFS) feature of Windows, which allows files and folders to be encrypted so that only users with the appropriate permissions can read them. The command is not designed for overwriting hard drive data or for permanently deleting files. Other tools and methods are available for securely erasing data, but 'Cipher' specifically focuses on the encryption aspect. Therefore, selecting the purpose of 'Cipher' as file encryption accurately reflects its functionality within the Windows operating system.
