Only way to open those is by running through the possible combinations until you find your password. Unless you used a common password that could be found in a dictionary attack. If it's not long and you know characters or phrases it includes or can eliminate some, it's possible. Otherwise a brute force attack with every letter small and capital, numbers and symbols would require a lot of computing power to go through and find the right password in a feasible amount of time.
