Like Winzip, GMail Can Create .ZIP Files Online
To create a ZIP file using GMail, compose a blank email message with Yahoo! Mail, Windows Live Mail or even GMail and put your GMail address in the "To:" field.
Upload and attach the files that you want to get zipped. (GMail supports attachments upton 10 MB in size.)
Once all your files are attached to the email message, hit the "Send Message" button and wait for that email to arrive in your GMail inbox.

Open the email message and you'll see a hyperlink called "Download all Attachments" - that points to the zip file created from all the attachments which you have uploaded in the first step.
You can save the zip file with all the attachments to your computer, or you can open it without saving.
While this you can create ZIP files in Windows without a third-party utility by sending files to the "Compressed (zipped) Folder", the GMail feature may also prove handy at times.

You've certainly run out of ideas ..
I don't get the idea behind using Gmail to create a ZIP. I can understand it when you have a lot of attachments already present and then download as zip, but actually uploading and then downloading the files again is just a sheer waste of bandwidth, both Google's and ours.
It's much easier to grab a free ZIP program.
It might be useful at times - not often. But see the terminology of google, how they think for the users and introduce new concepts at any given day.
The reason i came across this page is because i have a customer who doesn't have any zip facilities on their computer at work and they are prohibited from installing any programs on their work computers. So there is one reason :)
