What must be done with chronological files at the end of each calendar year?

Grouping chronological files together at the end of each calendar year is a key practice in data management and security. This process helps in maintaining an organized archive of records, making it easier to retrieve necessary documents when needed. By grouping files, it ensures that related information is stored cohesively, which can be beneficial for audits, reviews, and reference purposes.

This practice also enhances security and compliance with regulations, as it prepares the files for potential archiving or secure destruction according to the organization's data retention policies. It’s a proactive step in managing information efficiently and responsibly while recognizing the importance of keeping data structured for any necessary future access or review.
