Needs some work – Google Drive Review

Why did Google remove the password lock feature. Just because I want to let someone use my iPad doesn't mean I want them to get into my files. When you upload files to Google Drive it puts in the name of the file the extension type, which is confusing. You get file names like me.doc.doc, or you.jpg.jpg. Does Google not know that a file extension type is not a file name?
