Zip Viewer Pro - Unzip View is an iPhone application that allows users to easily open and view zip files directly from their email, other apps, or cloud providers. With this app, users can also open password-protected zip files, as long as they are in the PKWARE standard.

One of the key features of Zip Viewer Pro is the ability to drill down into the folder structure within the zip file. This allows users to navigate through the contents of the zip file and easily access specific files or folders. Additionally, users can edit or delete the content of the zip archive or the entire archive itself.

The app also provides the option to store files for later use, making it convenient for users to access their zip files whenever they need them. Furthermore, Zip Viewer Pro allows users to preview various file types within the zip archive, including iWork documents, Microsoft Office documents, Rich Text Format (RTF) documents, PDF files, images, public text files, music files, and video files.

Users can share their files via email, Twitter, or Facebook, and the app seamlessly integrates with other applications that support the file format, allowing for easy editing or printing via AirPrint. The functionality of sharing and downloading files is dependent on the user's device configuration.

Please note that the app does not contain any content after download. To use Zip Viewer Pro, simply touch on a zip attachment in your emails and choose to open the file in the app. From there, you can browse through the content of the zip archive.

Overall, Zip Viewer Pro - Unzip View provides a clean interface and delivers on its promise of efficiently handling zip files on the iPhone.
