Long hash from a large file
#1
Question 
Greetings, all! I am trying to recover a password for a large PKZIP file, which consists of folders and pictures inside these folders. I just learnt how to get the hash from John the Ripper, but sadly, the hash file is nearly 5kb, and copying it into cmd is unrealistic. Is there a way that, instead of just pasting the hash into cmd, I could use a txt file with the hash in it? 

Another thing is that I saw an old thread which mentioned that you could split a large file into smaller parts to crack it. But if it is already password-protected, how do you do that? Thank you all!!

yeah for sure, thats the preferred way after all (attacking hundreds or thousands of hashes simultaneously would be otherwise impossible), all you need is to get rid of the extra JtR infos like filename etc, see https://hashcat.net/wiki/doku.php?id=example_hashes on what is really needed for a particular hash

but be aware, zips or rars nowadays could produce hashes which are way to long for cracking

can you provide the link to that thread? i dont think this is possible (splitting file)
