Can a password unlock multiple files?

A password can indeed unlock multiple files, especially when those files are protected or encrypted using the same encryption method and share the same password. This is commonly seen in scenarios where files are bundled together or when a user chooses to apply the same password for different documents or data types for convenience.

In practice, many software applications allow you to set a single password for a group of files, making it easier to manage access without having to remember and input different passwords for each file. This approach enhances usability while maintaining a level of security.

While the other options may present specific scenarios or conditions under which files might be password protected, they do not encompass the broader ability of a single password to unlock multiple files across various contexts.
