Previously, when you received such a file, you had to go to all the effort of downloading the attachment and then viewing the contents. The time it takes when viewing multiple files can be considerable and frustrating, especially when you’re trying to keep track of what you’ve viewed.
But now it’s a lot simpler process. You can now view the contents of the RAR and ZIP files in your browser, saving bags of time.
And not only is that faster, but is far safer. If the viewing object stays in the browser, then you’re not actually loading its contents, meaning harmful viruses stay where they are, and not on your computer.
Come to think of it, this increased speed is great, but the added advantage of not having to actually open the file and therefore potentially download a malicious file, is perhaps as important.
Many viruses are delivered via emails with infected files and once you open the attachment, the damage is done. The file opens and embeds itself into the targeted computer, before the user is even aware of what is going on.
And depending on the complexity of the virus, it can either copy personal information and send it back to the originator of the virus, or it can literally take control and turn it into a ‘zombie’ machine, or make your machine do odd things.
So, a welcome enhancement for all users of Google Email attachments.
