Preview ZIP and RAR files from your Gmail inbox
You can now preview ZIP and RAR archives without downloading them. When you receive one of these types of archives, you’ll be able to browse through the files contained in the archive, preview supported files in Google Docs, and download selected items. This feature is also available on Google Docs for mobile.
How to access what’s new:
To preview any ZIP or RAR file in Gmail, click the ‘View’ button in the attachments area of the conversation. From here you can choose to download the file, preview in Google Docs, or print supported PDFs.
