Difficult to keep open without another person holding it open. We numbered each file numerically with the insert labels and attached a card with details of each number on it.
The file as is is fine. But I really wanted a plain ole cardboard brownish color expandable file one that would have cost only a few dollars. Think about stocking that kind.
I have bought several of these to store financial information in. It is very handy having a seperate pocket for each month and also have an extra pocket for the year long stuff that bridges multiple months.
