sqlDESKTOP is a computerized manual filing system arranged just like an ordinary office with pictures of real cabinets and real folders. You can arrange by project, by department or whatever makes sense to you. sqlDESKTOP doesn't tell you how to organize, it lets you do things your own way. Documents are easy to find because you don't have to remember the exact name of the document or where you put it. Instead, you can visually locate what you are looking for in a familiar office environment and click on it.
