But when I try a "unzip component-1.zip" for this file, its doesn't work :'( and the following message is displayed in Console:
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of component-1.zip or
component-1.zip.zip, and cannot find component-1.zip.ZIP, period.
