Explanation
Encryption transforms file data into an unreadable ciphertext that can only be decrypted and read by someone who possesses the correct key. This ensures confidentiality - even if unauthorized users access the file, they cannot read it without the key. Hidden folders only obscure file location but do not protect content. File permissions restrict who can access a file but do not make the content itself unreadable if the file is obtained by other means. Compression reduces file size but provides no security.
