seems interesting … why is it not supported by Google Labs … I mean the software is third party … BEWARE !!!
Additional Info:
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.
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.
