Abstract

Various embodiments illustrated and described herein include one or more of systems, methods, software, and data structures for package file presentation. Some embodiments generate visual representations of package files by extracting a list of display elements of a package file, each display element representative of a content file or a content folder including one or more content files included in the package file; extracting a presentation specification from the package file; and presenting a view of the package file as a function of the presentation specification and the list of display elements.
