These 'schemes' we use are attempts to thwart ignorant decisions or actions by our customers.Always better to set up 2 folders under each main folder of a job: "Active" and "Archived". As soon as you get a new art file, regardless of the name (final, final2, final_final_Last, etc.), move the old existing file to the "Archived" folder, then save the new file to the "Active" folder. You can't print the wrong file, if, you can't get to it (or, can you?)
