This command-line tool displays information about files that are encrypted with on partitions.
EFS is a feature of Windows that enables users to encrypt and decrypt files. Using EFS, users can protect files from unauthorized access to their sensitive data, including from a stolen laptop or external disk drive. Folders themselves are not encrypted, but are marked so that files that are created within them will be encrypted.
In EFS, users work with encrypted files just as they do with any other files, and the encryption is transparent. If the EFS user is the same person who encrypted the file or folder, then the system decrypts the file or folder when the user accesses it later. However, unauthorized users are prevented from access to encrypted files or folders.
For more information on EFS, see Encrypting File System overview in the Help and Support Center. For more information on NTFS, see NTFS: Getting Started in the Help and Support Center.
