I think I am misunderstanding how or what Insync really is. As I see it Insync keeps a folder in Dolphin synchronized as to the content of my Google Drive(s). Insync really doesn’t work from the client side by allowing me to synchronize the content of either all or specific folders and their content or sub folders content.
I have to first upload from my hard drive folders, sub folder and content that I want on Google Drive and then tell Insync where the new folder in Dolphin is that will synchronize with the contents of the Google Drive as just a place holder or indication of the content on the Google Drive.
Maybe another way to ask this is; after installing Insync can I tell Insync to just take my hard drive and allow me to choose which folder and content on my hard drive I want synchronized with my Google Drive. Such that when I save a file to a folder on the hard drive Insync sees the change and syncs the two either instantaneously or on a scheduled basis.
Please let me know if I am missing something here. What documentation you have provided really isn’t helpful.
