Automate the transfer of files

Is there a way to to automate the process of transferring & deleting files from G.Storage to G.Drive, as well as be able to manage authentication (gstorage & gdrive) in a completely automated fashion?

Once you have the remotes set up you can use “rclone move”. You could then put the command on the crontab. Is tht the kind of thing you were thinking of?

is it possible to provide credentials file to rclone?
