My goal is to save my documents in Google Docs and sync them automatically via File Stream. In previous versions of MacOS, I was able to link the Documents folder to the Google Documents volume.
Folder ~ / With / Volumes / GoogleDrive / My Drive / Documents Linked Documents / with:
sudo rm -rf ~/Documents #note this an empty directory sudo ln -s /Volumes/GoogleDrive/My Drive/Documents ~
This works fine until I reboot and the link is replaced by a folder.
