Can zend files be decrypted with a black knife or not?

Can zend files be decrypted with a black knife or not? I used a black knife 4.3 for decryption. some zend files can be decrypted. some encrypted files cannot be decrypted at all, that is, I decrypted the files and saved them to a certain path, as a result, no file exists, and some files can be decrypted normally. what is the problem? Please kindly advise me!

Zend has a version number.

How can we know the encrypted version number?

Does the file have version information at the beginning? But not the version number, but the version date.

I have the latest version.
