If for an app, do you have auto save activated for that app? MS Office and others have auto save features as user selectable options.

Open System Settings->General, Login Items and add/Delete what you want!

The email is either in an application or you're accessing it through a browser. Which? What is "anything else"? What kind of documents specifically.

Where are these documents/pdfs located when you open them initially?
