How to Password Protect a Folder in Windows 11 Home?

To password protect a folder in Windows 11 or Windows 10, a file encryption software is needed. is designed to protect the contents of your files by converting them into a secure, unreadable format using encryption algorithms. Here's what it does in detail:

1. Encrypts Files for Security

Uses strong cryptographic algorithms (e.g., AES, RSA, Blowfish) to scramble file contents.

Only authorized users with the correct key (password, passphrase, or digital certificate) can decrypt and access the original data.

2. Prevents Unauthorized Access

Protects sensitive files from hackers, malware, or unauthorized users.

Useful for financial records, personal documents, business secrets, and confidential communications.

3. Supports Different Encryption Methods

Symmetric Encryption (e.g., AES-256) – Uses a single key for both encryption and decryption (fast but requires secure key sharing).

Asymmetric Encryption (e.g., RSA) – Uses a public key to encrypt and a private key to decrypt (more secure for sharing files).

Go and find a good file encryption software in order to password protect a folder in Windows 11/10. The built-in bitlocker encryption is used for encrypting disk partitions. And it is only available in Windows 11 or Windows 10 Pro.
