What is the best file encryption software for Windows?

BitLocker is primarily designed for ​​full-disk encryption​​, meaning it encrypts an entire drive rather than individual files or folders. While this is excellent for protecting an entire system such as preventing unauthorized access if a laptop is stolen. However, it is not ideal for ​​file-level encryption​​ needs.

If you only need to secure specific sensitive documents (like financial records or personal files) without encrypting the whole drive, BitLocker is overkill. File-level encryption provides more granular control, allowing you to encrypt only what’s necessary while keeping the rest of the system accessible.

A dedicated ​​file encryption software for Windows offers better flexibility and precision. Unlike BitLocker, which requires enabling encryption for an entire partition, file encryption tools let you selectively protect files or folders. This is particularly useful in shared or multi-user environments where different users need access to different files. Additionally, file encryption software often provides more advanced features, such as password protection, expiration dates, and secure sharing options with capabilities that BitLocker lacks for individual files.

Another key reason BitLocker is not ideal for file-level encryption is its ​​dependency on the system drive and user account​​. If you encrypt a file with BitLocker, it's tied to your Windows user profile and system certificates. Losing access to your account or the encryption keys can permanently lock you out of those files.
