As a library administrator with the legacy AODocs Smartbar installed, you can prevent contributors from modifying the sharing permissions of files and subfolders directly in the Google Drive interface.
Important: If you're using the new Smartbar, you must prevent contributors from sharing documents in the AODocs interface.
1. As a library administrator with the legacy AODocs Smartbar installed, open a library in Google Drive.
2. Click the gear button and select Security center.
3. In the Security center dialog, select the Security tab.
4. Select the checkbox Only administrators can share files and folders.
5. Click Done to save.
Note: You may experience some delay to see the changes applied because AODocs needs to update the Google Drive permissions on every file in the Team Folder or Secured Folder. For example, for a library with thousands of documents, it can take several hours before the change is fully effective.
