GMail FileSystem!

Turn your GMail account into a 1GB of off-site storage:

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.

This is a great way to backup your important docs. The only downside is that it's limited to 10MB per file (the GMail attachement limit). Hopefully future versions will break up large files, then upload. Cool app though.. Thanks to 'Digital Wizard' for the link.
