Google Docs Viewer can now open zipped files in ZIP and RAR formats. The next time you get a zipped file in your Gmail inbox, you can click view and the Google Docs app will show files stored in the zipped archive right there in the web browser window. What’s more, you can download files from the archive or save them in your Google Docs account and edit them later. The best feature in my book, however, is it is supported on mobile versions too. So the next time a zipped file hits your mobile mail inbox, you know what to do.
