Important: If you open an AutoSaved file and then continue to work on it, it will not be autosaved. To continue working on an autosaved file and have it subject to autosaving, rename and save the file in a location 
		  other than where the autosaved files are found. 
		
Note:  
		The autosave file has the same name as the source file, followed by an incrementing number.
