Google Drive Auditor creates a detailed privacy report of shared permissions and access settings of all files in your Google Drive.
Google Drive Permissions Auditor scans all the files and folders in your Google Drive and prepares an audit report detailing who has shared access to your file in Google Drive and what level of permissions they have.
You get to know about the file's MIME type, the size of the file (handy if you are running out of storage space in Drive), the kind of access other users have on your files, the full path of the file in your Google Drive and the list of Google Accounts that have access to your files. You can click the file name in the privacy report to view or open the corresponding file in your Drive.
To get started, go to the Add-ons menu, choose Drive Permissions Auditor and then choose Start Audit.
The add-on is free but it will only scan the access permissions of ~200 files in your Google Drive. If you would like to audit every single file in the Drive, please upgrade to premium from https://gum.co/GA06
The Drive Auditor add-on is an essential security add-on for Google Drive as it will help you know if any important files and documents have been inadvertently shared outside your Google account or your Google Apps domain.
The auditor scans all files but you an use the search operator of the Google Drive API to limit your search to files that meet certain criteria. For instance, the following search query will only scan Google Spreadsheets that are owned by you.
"me" in owners and mimeType = 'application/vnd.google-apps.spreadsheet'
