Google Drive Windows – Google Drive for Multiple Windows Users

The solution of @pestul didn't work here. Even with diagnostics mode (C:\Program Files\Google\Drive>googledrivesync.exe --vv), the app failed to start.

So I deleted the C:\Users\*username*\AppData\Local\Google\Drive folder and the app started again. Of course you will have to re-enter your credentials and start the whole sync process from the beginning BUT the new GoogleDrive version (1.18.7821.2489) doesn't force you to start with an empty folder, meaning you can point to the old folder AND it now detects if the local files are the same on the server, eliminating the need to synchronize everything from scratch!

As an example, it took approximately less than 5 minutes to synchronize my 13.31GB folder with 60.063 files in it. In the middle of the process it will show a popup window telling you the number of files that exist only locally, the number of files existing only on server, and the number of files conflicting.

I'm sure there is some sort of license agreement for Google Drive which will answer your question about the legality of your endeavour.

I think the big issue is that it's not supported out of the box. The original Google Drive tool will not support you on doing that, and neither will you be able to access your drives on other devices such as your phone or tablet without messing with the settings all the time.

And, let's face it, current third party tools just aren't nearly as good and complete as Google's original.

So, yes, technically you can get more space but you lose much of the convenience.
