Frequently Asked Questions
What’s the simplest way to set up a filing system in a small home office?
Start by sorting papers into three immediate piles: active (current projects), reference (need occasionally) and archive (rarely needed). Assign a clearly labeled box or mailer to each category; place active files within arm’s reach in shallow boxes, reference files on a nearby shelf in stackable boxes, and archives in sturdier boxes stored higher or under a desk.
Are cardboard boxes a good choice for long-term document storage?
Yes, corrugated cardboard is fine for long-term storage if kept dry and away from pests. Choose stronger grades (ECT-32 or ECT-36) for heavier contents, and avoid basements or attics where humidity fluctuates. For critical legal documents, consider sealed plastic containers or a fire-/water-resistant storage option.
How do I keep papers labeled and easy to find in small boxes?
Use a consistent labeling system: month-year, client name, or project code. Apply printed labels or write directly on white or kraft box surfaces. Consider color-coding with stickers or using a visible index card in the front of each box to speed retrieval.
