In the InSync initial setup process for my local drive, I change the default path from C:\Users\ [Username]\firstname.lastname@example.org to my unit D: (main level, no folder) in the dialog window.
In the process setup for the remote unit (Google Dirve GSuite), I choose “Selective Folder”, I uncheck “share all folders” and I choose, for example, only the “Test” folder.
Then, at the end of the setup, I can see that InSync starts working and then I see that a “Test” folder has been created in my Local D: and all the files in the “Test” folder of my remote unit ( GoogleDrive) are synchronized to my local drive D:\Test. So far, all OK.
So, as I explained before, if I put a file in the GoogleDrive\Test folder, this file is immediately synchronized (replicated) in my local drive D:\Test.
— However — If I put a file in my local drive D:\Test, this file is never synchronized to my remote drive GoogleDrive\Test folder. This problem does not occur if I use C:\Users\ [Username]\email@domain or D:\SomeFolder (instead of D:) as a local drive folder.
I hope to have explained the problem in an understandable way, it is a little hard for me to write in English, it is not my native language.
