EFS (Encrypting File System)

Encrypting File System (EFS) is a built-in Windows feature that protects your files by converting them into an unreadable format unless you have the correct decryption key. Think of it like locking your files with a digital lock—only authorized users can unlock and access the data. This helps keep sensitive information secure from unauthorized access, even if someone gains physical access to your storage device. EFS is seamless to use; it automatically encrypts files you choose and decrypts them when accessed by authorized users, providing a balance of security and convenience.
