Unzip Problem Help

[mongoose8p]

I downloaded some video files from the internet today that was a total of around 2 gigs of video I'm trying to unzip them and I get this error in archive utility
"Unable to unarchive " " into " " (Error 1 - Operation not permitted)
When I try to unzip in terminal I get this error
Archive: Entourage.zip
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 Entourage.zip or
Entourage.zip.zip, and cannot find Entourage.zip.ZIP, period.


Any ideas... I get an error on windows computers too, however this is a torrent (Yes I know most don't support this) but on the comments of the torrent some people had trouble unzipping and some did not... I don't know what's going on

It sounds like you downloaded part of a segmented .zip archive. Until to download them all, you will not be able to unzip any of the segments.
