Error unzipping downloaded ismn data #23

Open awst-baum opened 4 years ago

awst-baum commented 4 years ago

Hi! For QA4SM, we've tried downloading the latest ISMN data and unzipping it - but we all get an error on decompression:

file #14549:  bad zipfile offset (local header sig):  21299
file #14550:  bad zipfile offset (local header sig):  796807
file #14551:  bad zipfile offset (local header sig):  1546605
...

This isn't a problem with the reader but I thought I've got to report it somewhere.

log.zip

I've also tried unzipping with jar (since that's recommended in the Internets) like this:

jar xvf Data_seperate_files.zip

That yields:
