How to run multiple Google Drive (no just one acount)
Install Google Drive (Sync) on PC. Is not need configure any acount.
Remove from autostart. (msconfig)
Choose and create all folders what you will want to use. (for exapme e:/GDrive-home/ e:/GDrive-work/ e:/GDrive-family/ )
Create run scripts here. C:\Program Files (x86)\Google\Drive\ I named they as "gdrive-home.bat", "gdrive-work.bat", "gdrive-family.bat". (need administrators authorization) or disabled UAC in system Windows
First run one as single and next run after complete previos configuration.
