Free File Lock is a Windows utility for encrypting individual documents, photos, videos, audio files, archives, PDFs and other files with a passphrase. It supports Windows 11 and Windows 10. Keep an unencrypted backup until you have tested that the protected file can be decrypted successfully.
Use a password to restrict casual access to sensitive business documents, personal photos, videos and other private files. Free File Lock protects files one at a time; it does not claim to replace BitLocker, device encryption or a complete backup strategy.
The program provides several cipher and hash choices. When available, prefer a modern option such as Rijndael with SHA-256 or stronger, and record the selected settings because the same choices are required for decryption. Legacy options such as DES, MD5 and SHA-1 are retained for compatibility and should not be your first choice.
The file lock also features with decryption function which helps decrypt your previous locked files. It brings you convenience to remove restrictions for anyone to access and share your files for editing, printing, listening, watching, etc.
Free File Lock is a lightweight and easy to use file encryptor tool which makes it ideal for complete computer novice. By following the brief instructions on the uncluttered interface you can lock any files in 3 steps. Most importantly, it is a totally freeware that means you can use & download it without spending a penny or register.
Encryption controls access but does not prevent disk failure, accidental deletion or corruption. Keep a separate backup of important files and verify that you can decrypt a test copy before removing the original.

Yes. Free File Lock is a separate desktop utility and does not depend on Windows Pro-only EFS features. Test the encrypted output before deleting the original file.
The program is designed for individual files. To protect a folder, encrypt the important files inside it individually or use an encrypted archive or drive. Do not describe a hidden folder as encrypted unless its contents are actually encrypted.
There may be no practical recovery method. Store the passphrase in a trusted password manager and keep a separate backup of important files.
Prefer a modern option such as Rijndael and SHA-256 or stronger when available. Avoid legacy choices such as DES, MD5 and SHA-1 for new sensitive data.
