Someone asked me these on Hackology FB Page ,
Available options : John the Ripper, ElcomSoft, Parallel Password Recovery
- Brute-force attack
- Dictionary attack
- Biham-Kocher attack (this attack is possible when you have part of the text)
- Stay attack (also plaintext based)
if you used a recent winzip (which is suspected since you encrypted this last year), the encryption is AES with a 128 or 256 bit key. This means you can do nothing more but try a bruteforce attack.
As you mentioned you know part of the password , therefore you may try Kimci86/BKcrack which utilizes the Biham-Kocher Attack
