This morning one of my very good friend pointed out to this website http://www.viksoe.dk/gmail
GMail Drive is a Shell Namespace Extension that creates a virtual filesystem around your Google GMail account, allowing you to use GMail as a storage medium.
GMail Drive creates a virtual filesystem on top of your Google GMail account and enables you to save and retrieve files stored on your GMail account directly from inside Windows Explorer. GMail Drive literally adds a new drive to your computer under the My Computer folder, where you can create new folders, copy and drag'n'drop files to.
Please note that GMail Drive is still an experimental tool. There's still a number of limitations of the file-system (such as total filename size must be less than 40 characters), and it doesn't make full use of the secure internet protocols available
If you are unable to download the installation from there you can find an alternate here.
