This was raised 2 years ago and there doesn’t seem to be any progress in finding a solution?
I’ve moved from Windows 10 to Ubuntu 16.04 so installed/ bought InSync to use as there is no Google Drive client for Linux.
I started my initial sync and the number of files in the queue is going up as other users add files to shared folders, our development environment generates files dynamically and new coding projects are added.
It started at around 360,000 now around 447,000 - this is madness, that number should be going down, not up.
From experience the Google Drive client could completely resync the same number of files from scratch in 1-2 days.
The multiple file sync feature should be top priority - it simply isn’t working for a lot of us in it’s current form.
