For those starting to use the Google repository (like myself), the file picker only displays, or deals with, documents with the Google Docs format; that is:
- Documents created directly on GDs.
- Documents converted to the corresponding GDs format.
Also, the file picker doesn't display the GDs folder hierarchy: files are displayed just as they are shown under the All items option (in GDs).
Once selected, files are copied into the Moodle data folder.
