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

About

Zas

Features

Send anything to your own devices — instantly, privately, and without the clutter. Zas moves a file, photo, video, or note from one of your devices to the others the moment you tap send. It shows up in real time, ready to open or save. When you're done, it clears itself, so nothing piles up and nothing lingers. WHY ZAS • Instant across your devices — send from your phone, and it's on your other devices right away. • Encrypted before upload — Zas encrypts content on your device. Storage receives encrypted bytes. The service keeps the account, channel, delivery, and expiry metadata needed to sync and remove items. • Big files in a blink — Zas recognizes content it has seen before, so a file you already sent goes through in about a second, whatever its size. • Cleans up after itself — items disappear after five days by default. Want to keep one? Pin it, and it stays until you let go. • Share your way — open a channel with someone, or make it read-only so they can view and download but not change a thing. React to items with a tap. • On every screen — on your iPhone and on the web, always in sync. HOW IT WORKS 1. Sign in with Google or Apple — no new password. 2. Tap send and pick a file, photo, or video, or paste text. 3. It appears on your other devices in seconds. Open it, save it, or let it expire. PRIVATE BY DESIGN Zas encrypts content on your device before upload. Storage receives encrypted bytes. The service keeps the account, channel, delivery, and expiry metadata needed to sync and remove items. Send to your devices. Share with your people. Leave nothing behind. Questions or ideas? We'd love to hear from you.
