What does EFS stand for?

EFS stands for Encrypting File System. This feature is integral to Windows operating systems, allowing users to encrypt individual files and folders to protect sensitive data from unauthorized access. With EFS, the encryption occurs at the file system level, which means that files are encrypted automatically when saved and decrypted only when accessed by the user with the appropriate permissions.

This capability is particularly useful in environments where data security is paramount, enabling users to maintain confidentiality. The system uses strong encryption algorithms to provide security for files, ensuring that even if someone gains access to the physical storage, they cannot read the contents without the necessary decryption keys.

The other options, while they may seem plausible at a glance, do not pertain to the specific functionality provided by EFS in the context of file encryption. Enhanced File System, External File Storage, and Encrypted File Security do not accurately describe the technology used to enable file encryption within Windows.
