I have this multiple-part zip files as a list of {File.zip.001, File.zip.002, ..., File.zip.013} that happen to be protected by password.
When I try to unzip them using the Gnome GUI, I see click on the first file and can see everything inside of the archive. When it comes to extracting one or more of the contained files, the GUI asks me for a password which I don't have.
I tried to run zip2john on the first file of the archive, and an error appeared:
Did not find End Of Central Directory
I understand that this is because the archive is split, so I tried to merge it, first using cat:
cat File.zip.* > reassembled-zip.zip
Which results in a single .zip file, that still outputs the same error with zip2john.
Then using zip -FF:

I think that the zip files are not broken, because the Gnome GUI tool has no trouble reading into the archive. But how can I bypass the password of the archive if john cannot process a multipart archive ?
