Getting started is easy. First, install the Google Drive Auditor add-on and authorize it. If you have been collaborating with people for some time, Drive Auditor is the easiest way to find out what you’ve shared in Google Drive and sanitize it.

Meet Permissions Auditor for Google Drive, a new Google add-on that scans your entire Drive and then generates a comprehensive report revealing who has access to your shared files and what kind of permission they have on the files. Would you like to know which files and folders in your Google Drive are shared with other users and what kind of access permissions they have on your files? Google Drive, unfortunately, doesn’t offer an easy option for you to figure out who you are sharing the files with either inside or outside your organization. These users could be your contacts, someone within your Google Apps domain or some of the shared files could be public meaning they are available to anyone on the web who have the link (URL) to the file. If you change someone’s access to “Can edit,” the expiration date will be removed.You may have a number of documents, spreadsheets and other files in your Google Drive that are accessible to other users.If you set an expiration for someone with edit access, they will only be able to comment on the file.Note that you can’t set expiration dates one files and folders for people with edit access: In such a situation, wouldn’t it be nice if you could set expiration dates while sharing files in Google Drive? For instance, share a document temporarily for, say, 10 days and access to the file should be revoked automatically after that period has passed.

For instance, if you have shared a document with an external vendor, they’ll continue to have access to the file long after your business contract may have ended. When you share any file or folder in Google Drive with another user, the shared links will work forever unless you manually change the sharing permissions.

Did you know that you can set a time limit on folders and files that you share via Google Drive? More information can be found here:
