Which feature allows Relativity to attempt decryption of multiple files simultaneously?

The feature that enables Relativity to attempt decryption of multiple files simultaneously is the Password Bank. This function acts as a centralized location where passwords can be stored, allowing for efficient management and application of decryption keys across various files without the need for manual entry each time.

By utilizing the Password Bank, users can streamline the decryption process significantly. Rather than working through files one by one, the system can access the stored passwords as needed and apply them to encrypted files in batches. This not only saves time but also reduces the risk of errors associated with manual input.

The other features listed do not directly facilitate simultaneous decryption. Batch Processing refers to the ability to work on multiple tasks or documents at once, but it does not specifically address password management or decryption processes. File Streamlining is focused on optimizing how files are handled and accessed, while Document Grouping relates to organizing documents within the system.
