I can’t tell if I’m sharpening incorrectly or if my file is just worn out. Is there a way to tell? I read somewhere to replace after like five sharpening a but that seems really short.

No, just use the card dry against the grain of the file. I learned about them back in metal shop in Junior Highschool, and they work very well.
