The scene's equivalent to Sony's [[Packages_(.PKGS)|PKGS]] format but in this case it's to be used with a [[HENkaku]]-enabled PS Vita or PS TV. It does not use any encryption over files so you can not install a '''VPK''' with the official PKG installer and vice versa. '''VitaShell''' can not install [[Packages_(.PKGS)|PKGS]] files.
