There are three situations where the suffix is incorrect. 1: The file itself is not encrypted. We can directly delete the suffix and the file can be used, or change it to the correct suffix and decrypt it without affecting its use. 2: When the encryption of a file is correct, we need to change its abnormal suffix to a normal one to decrypt it correctly. After the file is decrypted, it is normal. 3: If the file encryption process stops and the file is damaged, and we change it to a normal suffix,
it will not be decrypted either, because the file itself is not fully encrypted and its encrypted information is incomplete, so it will not be decrypted
