If you need something soft, you might consider looking at the best fireproof document bags, which serve a similar purpose to that of portable file boxes. Others may prefer portable file boxes with specific features, such as locks, as well as fireproof and waterproof materials.

If you’re going to be traveling with your file box, it’s important to get a file box that won’t degrade while you travel. Finding a durable portable file box isn’t exactly tough, but avoid anything cardboard or in soft fabric that may become misshapen over time.


File boxes often contain important documents, which is why many elect to get portable file boxes that are as secure as possible. Choose a portable file box with a lock or multiple locks, and opt for ones that are fireproof and/or waterproof.

How much you can expect to spend on a portable file box
