Handling home office equipment - hanging files

We have a single draw file cabinet for items that can't be paperless. Packing it full seems to work OK.

But as others have said, unless you really need a physical piece of paper (say a truck title or such), avoid it. Non-critical paperwork (receipts, utilities, etc...) we take a picture and save it to a portable hard drive (we do back up the hard drive periodically also).
