このスレッドは現在死んでいる可能性がありますが、データベース内のフォームを操作していて、ユーザーが一意の識別番号を持つフォームに表示される特定のレコードにファイルを添付する必要がある場合、これは間違いなく可能ですが、実行する必要があります.NET で記述された外部アプリケーションでは、開始するために必要なコードを提供できます。vb.net は VBA に非常に似ています。
Windows フォーム プロジェクトを作成し、Microsoft アクセス コア dll への参照を追加し、ナゲットから Google ドライブ API のナゲット パッケージをダウンロードする必要があります。

このコードはドライブ サービスを承認し、インポートの下にパブリック共有サービスを DriveService として作成します。これは、任意のサブまたは関数から使用できます。次に、フォーム ロード イベントでこの関数を呼び出します。
サービス = GoogleDriveAuth.GetAuthentication
プロジェクトへの参照を Microsoft Access 12.0 Object Library または使用しているバージョンに追加します
次に、このコードは、レコード番号の値を取得したいフォームを調べ、選択したフォルダーにファイルをアップロードします
