I use sometimes Google Drive for sharing large files. Google Drive is fast and user friendly.
I don't wish that Google sees the content of my files and try to encrypt the filename and content. My question is it really secure (Google sees only data trash) or should I optimise my command? I generate a 30-50 character password. I need to use 7zip, because I share files for non-tech-savy users.

Quote from Reasons not to use Google by the pioneer Richard Stallman.
Google shut off Alexa O'Brien's Google Drive account, denying her access to it, because her reporting on Chelsea Manning's trial included copies of al-Qa'ida propaganda that was presented as evidence.
