What's the best way to organize files inside a fireproof cabinet?

Use hanging folders on the integrated suspension rails the same way you would in a standard lateral cabinet — the drawer system works identically. Organize by retention schedule: documents coming up for review or destruction go in the most accessible drawers, long-term storage goes lower. Don't overfill drawers — compressed files make retrieval harder and can interfere with the drawer seal. Store your most irreplaceable originals in the best-protected location (typically middle drawers, away from the door and base).
