The Windows 2000 Encrypting File System (EFS) is an enhancement available only to the Windows 2000 version of the NTFS v.5 file system. It allows users to encrypt/decrypt files on the fly to protect sensitive data from unauthorized access, while still providing for data recovery by the administrator if a user loses/deletes their keys or leaves the organization and their profile is removed before the files are decrypted.
