Quick verdict: A handled letter-size file case with a secure latch is the best choice for most mobile paperwork because it protects documents better than an open folder. Accordion-style cases are better when category separation matters more than rigid protection.
Portable file cases sit between an expanding organizer and a full file box. They are designed for papers that need to travel without getting bent, scattered, or mixed together.
