Best way to keep organized Overall, it can really make your life easier and more organized, highly recommended! This is such a great tool for keeping track of your pdf flies while categorizing them to fit your preferences. As a student, I've used this for many different reasons and have always found it extremely convenient for filing and organizing my files. From school assignments to the official paper work, it provides a user friendly platform for easy usage and proper description. Must have for the student to the average daily worker! It can be a little tricky to figure out how it functions properly at first, but their are some good tutorials out there that I highly recommend, such google them. Also, it doesn't really have a customer support system, which is a down side.
