The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption. The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
Filesystem-level encryption, [1] often called file-based encryption, FBE, or file/folder encryption, is a form of disk encryption where individual files or directories are encrypted by the file system itself. This is in contrast to the full disk encryption where the entire partition or disk, in which the file system resides, is encrypted.
BitLocker uses a low-level device driver to encrypt and decrypt all file operations, making interaction with the encrypted volume transparent to applications running on the platform. [41] Encrypting File System (EFS) may be used in conjunction with BitLocker to provide protection once the operating system is running. Protection of the files ...

DPAPI doesn't store any persistent data for itself; instead, it simply receives plaintext and returns ciphertext (or conversely).. DPAPI security relies upon the Windows operating system's ability to protect the master key and RSA private keys from compromise, which in most attack scenarios is most highly reliant on the security of the end user's credentials.
Transparent Data Encryption (often abbreviated to TDE) is a technology employed by Microsoft, IBM and Oracle to encrypt database files. TDE offers encryption at file level. TDE enables the encryption of data at rest, encrypting databases both on the hard drive and consequently on backup media. It does not protect data in transit nor data in use.
Encrypting File System (EFS) in Windows Vista can be used to encrypt the system page file and the per-user Offline Files cache. EFS is also more tightly integrated with enterprise Public Key Infrastructure (PKI), and supports using PKI-based key recovery, data recovery through EFS recovery certificates, or a combination of the two.
