This tutorial explains how to check who has access to your Google Drive files and folders.
WhoHasAccess.com is a free webapp that helps to generates a list of all those people with whom your Google Drive files and folders are shared. Manually, it will be time-consuming to check each and every file/folder to know with whom you have shared your Google Drive content. But with this handy webapp, you can easily see all the people who can access your different shared files and folders in a single web page.
You can also click on the name of a particular person to find out what you have shared with that particular person. Revoke access option is also provided, but unfortunately this feature is not available yet. However, you can click on file/folder to access it directly on your Google Drive. After that, you will be able to manually change shared settings.
In screenshot above, you can see the list of people with whom I have shared my Google Drive files/folders. It will also notify you about the content shared by you publicly.
