"c:\program files\google\drive\googledrivesync.exe" --child_process --profile_id user_ambdASDADAS

Let Backup And Sync Child Account Appear On System Tray

Tips:

  • Change the profilie_id user_ambdASDADAS with your child Backup and Sync account default folder. And you can get the folder name at the location:

%localappdata%\google\drive\user_*** (under the c:\users\user name\appdata\local\google\drive folder, and *** means a random string)

  • The primary Backup and Sync account default folder called user_drive located on the same path.

  • If you have the third Backup and Sync account, you could do the same command with the right default folder to make it appear on the system tray.

After all the instances appear on the system tray, and then it will sync the files again. And the Backup and Sync account already in use error message will be solved easily.
