I created a Google drive folder to which I gave an access to multiple people.
These people have created sub folders inside this and have created multiple Google docs inside these. They are now the owners of these Google docs.
I want to remove them from being owner of these Google docs. One way is to manually ask them but it's very difficult as there are hundreds of documents.
How can I remove them from being owner of these doc's that they have created inside my Google drive?
