![]() * EFS takes the FEK, encrypts it using the public key, and then stores it with the encrypted file. * To add a much greater level of security, EFS also encrypts the FEK using asymmetric encryption. How EFS works: * EFS creates a file encryption key (FEK) for the file or folder. You can't use encryption with compression. The encryption keys needed to decrypt the file do not exist on these other systems. ![]() Files remain encrypted and inaccessible even when the drive is moved to another computer or another operating system is used. Moving an encrypted file to a non-NTFS partition removes the encryption. Where is EFS available? Only on NTFS partitions. With EFS, you can allow other users to access the decrypted file. ![]() Windows automatically decrypts a file when the file owner accesses it. Encrypting File Service (EFS) Encrypts individual files.
