Once a file is Portable- or Diamond encrypted it cannot be opened and decrypted without the correct password, and we will not be able to help you retrieve your password.
This is because the file has been encypted into a ciphertext with the password you set. Only entering the password you can decrypt it, so please keep the password firmly in your mind.
Try the following methods to help you remeber your password:
1. Case sensitive: Many wrong password errors are actually wrong case errors, so make sure to enter each character in your password in the proper case.
2. Width sensitive: Change between full-width and half-width characters and symbols.
3. Wrong password: Try your commonly used passwords.
