With the AODocs Smartbar installed, library administrators can prevent contributors from modifying the sharing permissions of files and subfolders.
1. In Google Drive, open an AODocs library where you are defined as a library administrator.
2. Press the gear button and select Security center.
3. In the Security center window, select the Security tab.
4. Select the checkbox Only administrators can share files and folders.
5. Press 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.
