GMail Drive
Just downloaded and installed GMail Drive.
“ GMail Drive is a Shell Namespace Extension that creates a virtual drive in the Windows Explorer, allowing you to use your Google GMail account as a storage medium. We are filing this one under the "We wonder how long Google will let us get away with this" category. Anyone care to place bets? (Our guess is less than one week.) “
What a great tool to use for online storing of files.
