The Google Drive Drawing link is a proprietary shortcut file format created by Google to bridge local desktop environments with cloud-based content. These files function primarily as pointers, allowing users to launch and edit cloud-hosted vector graphics directly from local file explorers via the default web browser. As these files contain only metadata and resource locators rather than executable code or binary image data, they present minimal security risks to the end user.
