Sometimes you have multi-part zip archive file like: *.z01, *.z02, *.z03, *.z04, *.z05 and *.zip.
You try to extract the ZIP with usual way like ‘right-click’ > ‘extract here’ in the file manager, or doing ‘unzip *.zip’ in the terminal, but its seems not working and you find the error code like:
warning [/home/monotoko/Desktop/NT51%2BWP2_CTFORUM(2).zip]: zipfile claims to be last disk of a multi-part archive;
attempting to process anyway, assuming all parts have been concatenated
together in order. Expect “errors” and warnings…true multi-part support
doesn’t exist yet (coming soon).
file #1: bad zipfile offset (local header sig): 4
Ok. This is what you should do to handle multi-part archives in Ubuntu. Going to terminal and write this command:
cat *.z01, *.z02, *.z03, *.z04, *.z05, *.zip > complete.zip
Anyway you can change the file name of ‘complete.zip’ to your extracted file.
In my opinion, the conclusion in this case: if you have multi-part archives in Ubuntu, whatever it is, you shoud concatenate the parts first. And you should concatenate them on the correct sequence. That is it :)
