I'm trying to unzip a zip file which contains a video... right away it says:
7-Zip  9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18 p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)
Error: /home/cyberproxy/Downloads/Floating1a.zip: Can not open file as archive
Unzips on my Android, unzips on my Windows desktop, unzips on my mother's iOS device with unzipper app.
What can I do to fix this?
