CAB at a glance
CAB
Convert to CAB when the destination is a Windows-specific packaging or deployment path, such as driver distribution, update packaging, or installer-related workflows.
It is useful when downstream tools explicitly consume cabinet archives and when keeping alignment with Microsoft deployment conventions matters.
For generic handoff or downloads, ZIP is usually simpler; CAB is the right target when Windows infrastructure expects it.
WAR at a glance
WAR
Convert to WAR when packaging a Java web application for deployment to a servlet container or Java application server.
It is appropriate for traditional web apps, admin consoles, internal portals, and enterprise services that still ship as WAR artifacts through CI/CD.
Use WAR only when the destination platform expects Java web archive semantics; for generic bundles, ZIP or TAR are better choices.
