Google Docs have added support for archive file types ZIP and RAR. While you can already use the Google Docs Viewer to view over 15 different file types in Gmail without downloading them.
Now, if someone sends you a ZIP or RAR file in Gmail, you’ll be able to view its contents from within your browser by clicking on View.
This will bring up a view that includes all of the files in the archive, the file types, and the size of those files.
When you hover over the list you can activate a menu by clicking the “Actions” button. You’ll be able to View items supported by Google Docs Viewer and Print (PDF) those that google docs offer PDF support. Save to Google Docs and Download appear for all files.
ZIP and RAR archives that are embedded inside other archives also work. For example, if you have a RAR file inside a ZIP file (like in our example above) you can just click on that file to access the embedded archive.
This removes the need to download full archives when you only need to work on select items.
This feature extends to Google Docs for mobile, too. For each viewable file (including embedded ZIP or RAR archives) there is a link to view.
