Folder Lock

Folder Lock is a comprehensive file security application designed to protect sensitive data through password protection, encryption, and secure storage across files, folders, drives, and portable media. With over 55 million users worldwide, it offers a robust suite of tools including on-the-fly file encryption, encrypted virtual lockers, cloud and automatic backup, a built-in password wallet, file shredding, and a Stealth Mode that hides protected folders from view — making it one of the most feature-rich consumer-grade security solutions available for Windows 10 and 11. The software is primarily suited for individuals, freelancers, and small businesses — particularly those in information technology, financial services, and professional services — who need to safeguard client records, financial documents, passwords, and confidential project files without the complexity of enterprise-level security tools. Common use cases include securing data on shared or stolen computers, encrypting USB drives and portable media, maintaining privacy for personal or professional records, and ensuring sensitive files are permanently deleted rather than simply removed. Priced at $39.95 per year with a free version also available, Folder Lock strikes a balance between affordability and functionality that appeals to business owners, accountants, IT professionals, educators, and independent consultants alike. Reviewers consistently praise its intuitive interface and reliable protection, though some note occasional compatibility issues and inconsistent customer support responsiveness.
