To me, the help for AutoSave is not clear that it helps to recover after a crash, in the tools->options dialog it says:
"When set to On, AutoSave is enabled. AutoSave creates temporary files in the autosave directory of the user config. These files are deleted thenext time AutoSave occurs (on save or file close) and when the editor is closed."
What are these temporary files that are created? Are they unsaved files that I was editing? Or are they configuration files, such as keeping the list of most recently opened workspaces?
