About 6-7 years ago. I had a friend who still had some files on a 5-1/4 floppy. I kept an old Win95 PC specifically with a bunch of old drive types and a DVD burner, so I could rescue old files & move them to DVD. Sadly, that PC stopped booting about 2 years ago. I did consider trying to resurrect it, but neither of my current PCs even have a built-in DVD drive, so I think it's safe to say that moving files to DVD isn't moving the files forward enough anymore.
