Hello Maxim, 

pleased to meet you. My name is Shelby and I am working under Jacque Larson. We both employ the program google drive file stream to sync Google drive to our computers so we may access a shared work database. 

We have been running into this same issue of CAD file copies being created as you noted below. Given the structure of our work, at this time all of our files are saved to Google drive. I am not sure we could save the files elsewhere.

Since this post I am replying to is now almost three years old, is there some alternative solution we might find? For example, I heard there is a way to limit working on a file to just one user? Any information you have would be greatly appreciated. 

Thanks!
