If you have a GMail account more than likely you have lots of space to spare. I ran into a utility that allows you to mount your GMail account as a hard drive in windows.
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. The e-mail appears in your normal Inbox folder, and the file is attached as an e-mail attachment. GMail Drive periodically checks your mail account (using the GMail search function) to see if new files have arrived and to rebuild the directory structures. Because the GMail files will clutter up your Inbox folder, you may wish to create a filter in GMail to automatically move the files (prefixed with the GMAILFS letters) to your archived mail folder.
You can download the utility here.
This tool has been available for a while now. I believe the most up to date version is now 1.08.
Ethan, yep I saw it a few months back but never used it. I downloaded and installed it today so I figured I would mention it.
