Sometimes they can learn
Back in the early 90's, before our company had a network at all, I had a boss who loved to save everything on floppies because she moved between work and home computers. I told her she should save on the HD and copy to floppy for backup/transport, but she didn't listen and kept saving to floppies. Then one day she had a 400 page critical file she was working on refuse to open in WordPerfect.
I fired up some of the good old-time Norton Utilities and managed to get it to open in WP, losing only about 3 pages or so. I repeated my advice about using the HD as her primary save location and using floppies for backup/transport. She listened that time.
