Unzip Error 1

Hi,

I've been having some trouble unzipping some large files. I have two that I am getting that same error for, "Unzip Error 1". One is 5.56 GB, the other is 23.32 GB.

(Yes, I know these are huge. The smaller one was something I was putting on my backup drive and I zip just about everything to save space and keep it simple--of course got a call that they need a change on the file. The larger one was stuff from a friend's SD card that I had to take off in an emergency, and had to zip to save space.)

I tried doing it through terminal, here's what I get:

|| 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 /Users/HWH/Desktop/For Backup Drive/Kiss the Limit/HOTG Photo Reel.zip or

|| /Users/HWH/Desktop/For Backup Drive/Kiss the Limit/HOTG Photo Reel.zip.zip, and cannot find /Users/HWH/Desktop/For Backup Drive/Kiss the

|| Limit/HOTG Photo Reel.zip.ZIP, period.

Any ideas? Thanks very much!
