Color coded files are great for a home office. I use them and love the ease of finding something quickly. I like using Green, for instance, for everything related to finances, investing and money. I use red for closed issues where I need the paperwork but don't need to take action or refer to them frequently. Use your creativity and decide what categories you want and then match them each to one of the many colors you can easily get at Staples or Office Depot.
