MyWinLocker application has no feature or way which will enable you to recover your encrypted data without the Master Password
. There is no way the encrypted files can be accessed in the form they are. If you forgot you Password Hint then I am afraid that your files will be lost forever. The software has been created in such a manner that if someone has access to the encrypted files, it has no way of decrypting them without the software and the password which is equal to a case you forget your password. Any other solution fails to exist under such conditions.
Also you won't be able to access the files if you perform a new installation because the previous files contain the password which is required for decryption and since you don't know the password, you can't do nothing about it!
