How to lock a folder in external hard drive for Windows PC?

When you locking a folder in external hard drive, it's important to avoid certain errors that can lead to data loss, access issues, or security vulnerabilities. Here are some common errors to watch out for:

1. Using unreliable or pirated encryption tools that may corrupt data or compromise security. Use reputable, well-reviewed software or built-in OS features.
2. Locking a folder in external hard drive without creating a backup. If something goes wrong (software crash, corruption), you risk losing access to data. Always back up important data before applying security measures.
3. Setting a password or key and then losing it, which can make data irrecoverable. Use strong but memorable passwords, and store recovery keys securely.
4. Setting overly restrictive permissions that prevent you from accessing your own data later. Review permissions carefully and test access after setting locks.
5. Encrypting folders without understanding the process or implications, leading to potential data loss.
6. Use encryption methods you understand and ensure you know how to decrypt or unlock files later.
7. Locking a folders in external hard drive with software or methods incompatible with your operating system or future devices.
8. Ensure the locking method is compatible with all systems you plan to use.
