Office storage is a big problem for many small or medium-sized businesses. Space is at a premium, especially in urban areas. And no one can keep expanding their office so that there is room for all the historical data and information that you need (but don't know where to store).
Also, how will you even use that information? No one is going to dig through file cabinets looking for information that could be helpful but will take way too much time to rediscover.
