What is Folder Warden?
Folder Warden protects folders on Windows by locking, hiding, or encrypting them with a password. It keeps each folder in its original location and does not rename or move your files. Locking works quickly, while AES-256-GCM encryption adds stronger protection for sensitive data. You can also use a recovery key if you forget the master password. The program checks each lock or access change before reporting that the action was completed.

Key Features
- Lock folders instantly without renaming, moving, or packing them into containers.
- Encrypt files with AES-256-GCM and derive keys with Argon2id.
- Hide protected folders separately from locking and encryption.
- Verify each lock and unlock action against the folder before reporting success.
- Recover access with an offline recovery key if the master password is forgotten.
- Add folders through drag-and-drop or the Explorer right-click entry.
- Decrypt protected data without a license, including after reinstalling the app.
