zip file cracking

[Novus]

I encrypted a file with a simple numerical password. but when I go to hash it, I get an error talking about it being oversized and attempting to truncate the file. after realizing that zip2john wouldn't work, I then tried 'zip2john -c file'. running it through again after removing the file names and just leaving the $pkzip2$ on both the front and end, it will run for a second but not give an output. knowing that it's compressed, I chose 17200 even know it's only a checksum file. after that, I tried 17230 thinking that the format was the issue. both times saying 'no hashes loaded'

I'm still fairly new to this and can't figure out for the life of me what's wrong.
