Why, the hell, another zip cracker? fcrackzip isnt just any other file cracker, it is quiet old (born in 1998) and I believe the last version was from 2004. However it is simple mentioned for being the first open-sourced zip-cracker out there.
fcrackzip searches each zipfile given for encrypted files and tries to guess the password. All files must be encrypted with the same password, the more files you provide, the better.
