If you're on a Chromebook, yes, you can add files to your Create project from your Google Drive. See Using Create on a Chromebook.
To add media from Google Drive on another type of computer, either:
- download the files from Google Drive to your computer and then add them to your project from there, or
- locate the synced Google Drive folder on your computer and add the media file from there (if your Google Drive files are synced with your computer)
Create currently only supports adding media files from your computer, not directly from online storage providers. We may add a direct upload feature from online drives in future releases.
