What is the best file encryption software for Windows?

When using file encryption software on Windows 11/10, it's important to be aware of potential errors and pitfalls that could compromise your data security or lead to data loss. 

1. If something goes wrong during encryption (corruption, software failure), you could lose access to your files. Weak passwords can be cracked, defeating the purpose of encryption. Use strong, unique passwords or passphrases for encryption keys.
2. Some file encryption software may not be fully compatible with Windows updates or other security features. Test the software thoroughly, especially after OS updates, and ensure it’s reputable and maintained.
   Losing encryption keys or passwords can make your data permanently inaccessible. Store your keys/passwords securely, such as in a password manager.
3. Encrypted files may become accessible to unauthorized users if permissions are not correctly set. Ensure proper user permissions and access controls are configured.
4. Some encryption algorithms are weaker or deprecated, making data vulnerable. Use reputable, industry-standard encryption algorithms (AES-256, for example).
5. Encrypting files or folders without adjusting permissions can lead to access issues. Review and set correct NTFS permissions after encryption.
6. Encryption is one layer of security; neglecting other security measures can still leave your data vulnerable. Use comprehensive security practices, including strong passwords, secure storage, and regular backups.
