D³ — Drive Directory Duplicator

D³ is a lightweight, secure browser extension designed for the single, narrow purpose of recursively copying folder structures in Google Drive. Google Drive does not offer a native way to duplicate folders; D³ solves this limitation by providing a clean, one-click cloning tool directly in your browser.

It runs 100% locally in your browser sandbox, sending data directly to Google APIs. Your files and credentials never leave your browser, ensuring maximum privacy and compliance.
