Therefore, the Google Drive permission system is best understood as a policy enforcement tool rather than an impenetrable encryption lock. It signals intent and legal boundaries to the user. For Editors, the ability to download is a necessity of their workflow; for Viewers and Commenters, the lack of download rights serves as a digital "Do Not Touch" sign.

The "Commenter" role bridges the gap between passive observation and active participation. This role includes all Viewer capabilities but adds the ability to engage in a discourse surrounding the document without touching the body text.

Cloud-based collaboration tools like Google Drive have redefined document workflow. However, the relationship between permission levels (Viewer, Commenter, Editor) and the action of downloading files remains underexplored. This paper analyzes how each role influences a user’s likelihood, purpose, and method of downloading a shared file. Using a mixed-methods approach—surveys of 200 knowledge workers and log analysis of 1,500 shared documents—we find that Viewers download most frequently (to retain offline access), Commenters download least (preferring inline feedback), and Editors download in batches (for backup or repurposing). We conclude with design recommendations for permission-aware download tracking.
