GMail Drive

What is GMail Drive?

• Creates a virtual filesystem on top of your Google Gmail account
• Save and retrieve files stored on your Gmail account directly from inside Windows Explorer
• 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.

Caveat:

• Total filename size must be less than 40 characters
• The file size cannot exceed 10MB.
  
• Since the tool hooks up with the free Gmail Service provided by Google, changes in the Gmail system may break the tool's ability to function.
