Hello Nelly Nel,
Please follow the steps provided below:
1) (Re)install Parallels Tools as suggested at: http://kb.parallels.com/4841
2) Ensure that shared profile is enabled: VM config (http://kb.parallels.com/117287) > Options > Sharing > Turn ON Shared profile.
Make sure to have Google Drive installed on your Mac, so that you can find it under the Network location on your Windows VM.
Please drag the Google Drive from the Network Location to favorites and then you should be able to access it.
To access the Network Location, Go to Computer in your Virtual Machine.
You may also try rebooting your Mac and restarting your Virtual Machine.
