- Encrypting File System. Strengthens security by encrypting files on the hard disk so
that no one can access them without using the correct password.
Encrypted files are visible only to the individual who encrypted them. This is handled seamlessly by EFS, so the owning user can still browse and open files as normal - at the same time preventing others from doing so. Encrypted files can also be recovered using the recovery agent - which uses certificates and public keys to decrypt files.
