Can I use PKZIP for OS/400 v5.5.x to view/extract a 5GB archive created with PKZIP v5.6.x or higher?
Versions of PKZIP for OS/400 prior to 5.6.x will not recognize ZIP 64 features and will be unable to view or extract any files in your archives that are dependent on ZIP64 features. Also, any ZIP compatible programs you may be using from other companies will not be able to access all of the contents of your large archives. They may report that an archive is too large, or they may incorrectly report that the archive has errors. To ensure access to data in your large archives, always use genuine PKZIP from PKWARE.
