Which feature of the MPES assists in maintaining past project records?

The correct answer is the archive module. This feature is essential for maintaining past project records as it serves as a repository where completed projects and associated documents can be stored securely. The archive module allows users to retrieve historical data when needed, ensuring that important information is not lost over time. This is particularly beneficial for reference, audits, or when analyzing trends from past projects.

While the other options may offer some functionalities related to data management, they do not specifically serve the purpose of preserving historical records to the same extent as the archive module. The download history may help track files that have been accessed, but it does not inherently store project data long-term. The reporting module focuses on generating analytical insights rather than retaining past records. 'My files' typically refers to user-specific files rather than a comprehensive system for archival purposes. Therefore, the archive module is the most suitable choice for managing past project records effectively.
