That's not really fair to say. He/she may honestly not know and it's not fair for you to judge them. At one point I wasn't so savvy on this stuff and was making mistakes myself. It wasn't until I got a hold of better copies of recording that I owned that I figured out I was loosing quality with the lossy files.
Then they shouldn't be recommending things. What this person suggested would take a lot of time and result in a giant mess for any poor individual that actually did it. Don't underestimate how quickly bad advice can travel.
