Can't Move Google Files into Vault

[Michael]

that’s actually not possible (upstream bug as far as I understand)

Cryptomator won't accept Google docs

This is not an error specific to Cryptomator, see To answer your other questions: Maybe, you should try as suggested in the above article Googles Backup & Sync. In contrast to Google File Stream it holds always a local copy of your files. Local means that the gdoc file is stored on your harddrive outside of Google drive. So no. There is also no way to access your vault content from the web interface.
