The ability to store documents in one place, search through them all at once or by specific criteria very easily. It is also easy for users who are not as tech savvy but want access to their files when they need it. I have had problems with some of the features that do work well though - like searching across multiple folders/subfolders within your account. If you're looking for something simple yet powerful then this might be what you've been waiting for! We use docworld primarily so our employees can view any document stored anywhere without needing another copy (which is always in an outbox somewhere).
