Open KMZ files with your iOS device! KMZ Loader is designed to open KMZ files, which are compressed KML (Keyhole Markup Language) files. Google Earth can open KML files on its own, however KMZ's will not load properly without being decompressed first. KMZ Loader can decompress a KMZ file into a KML file allowing it to be viewed both in Google Earth and as source code. Any KMZ files imported into KMZ Loader will be stored in My KMZs and can be deleted by simply swiping over it. For more information on KML files: http://en.wikipedia.org/wiki/KML
