I have an 8.3 gig zip containing tons of telescope observation data, but I can't extract no matter what I try. I've tried Archive Manager, unzip, and tried this guy's fix: using zip -FFv to repair the archive. I'm also going to try putting this on my Windows system and running it there, but if there is anyway I can extract this file sharing that would be most appreciated. I'm running CentOS at work and have Windows 7 Ult at home.

Use rather 7z x

The default unzip %x fails to extract any .zip files larger than 4GB.

Instead, use the command 7z x

Be careful though, unlike unzip %x which creates a new directory, 7z x will extract in the current directory. The option -o allows to specify an output directory.
